Answer . There are bags that are made for specifically this purpose. I cannot remember the name, but there was an infomercial for these about a week ago. They claimed to be reusable 10 times and were quite cheap.
Carbon and hydrogen . Ethylene is composed of carbon and hydrogen. It's molecular formula is C 2 H 4 . In the Lewis dot structure, the two carbons (C) are connected with a double bond, and there are two hydrogens (H) attached to each C, so it looks like this:. H 2 C=CH 2 . See the Web Link…s to the left for more information. (MORE)
Ethylene gas in biology, is known as a hormone. Hormones, as they do in humans, cause growth. Producers of produce use a process that they "gas blast" the fruit or veggies to have them mature faster so they can go to resale faster. Produce that is exposed to ethylene gas isn't as flavorful, but they… do make a quick alternative to slow ripening. According to the infomercial I just saw, Ethylene gas causes fruit to spoil faster... It directly impacts the ripening process. Commercial growers/shippers use the concentration of the gas (either keeep it low to inhibit ripening, or increase it to increase ripening). many fruits will release ethelene gas as they ripen, for example bananas, and other fruit may react to it by ripening faster. fruit that reactes to external ethelene gas are called climactric fruit. --This is not necessarily the whole truth. Ethylene gas does not take away flavor, but actually adds flavor by breaking down starch into sugar using the enzyme alpha-amylase. This is the reason why produce markets use ethylene to ripen fruit when they arrive so the fruit can obtain their flavor when they hit the shelves. If ripening occurs naturally, fruits would sit on the shelf longer, and in the business world that hurts the inventory turnover rate. You're really going to listen to what an infomercial has to say? Ethylene causes fruit to RIPEN faster, spoiling occurs at the end of the ripening process. ..So, how is the food value of fruit that is 'gas blasted' effected? (MORE)
Ethylene is produced by heating hydrocarbons to intense heats. Theresulting mixture is then repeatedly compressed and distilled toremove the ethylene from it.
Ethylene glycol (IUPAC name : ethane-1,2-diol; Chemical formula C 2 H 6 O 2 ) is an organic compound widely used as an automotive antifreeze and a precursor to polymers. In its pure form, it is an odorless, colorless, syrupy, sweet-tasting liquid. Ethylene glycol is toxic, and ingestion can result …in death. (MORE)
Ethylene is derived from crude oil. The process of fractional distillation is used to separate crude oil into its main components (ie. its relevant carbon chain length). The cracking of the large hydrocarbons, thermally or catalytically, breaks them into smaller hydrocarbons. Ethylene is produced in… this way. (MORE)
Ethylene is a hydrocarbon that is commonly found in plants sinceits main function is being a hormone for plants. This product isalso used to ripen fruits.
One aspect of ethylene is that it is a plant growth hormone that causes fruit to mature. Chemically it is a hydrocarbon (alkene) with the formula H 4 C 2 (structurally H 2 C=CH 2 ). The double bond between the carbons makes it easy to react in the formation of many chemical compounds.

Ethylene gas is a ripening agent produced naturally by all plant tissue. Automotive emissions, plastics, smoke and fluorescent lights all increase ethylene gas levels, as well. When fruits and vegetables are growing in the ground, ethylene gas plays an important role in their life cycle and even hel…ps them become colorful and tasty. After harvest, however, ethylene can become a plant's worst enemy, causing fruits to ripen and decay, vegetables and flowers to wilt. Because plants produce ethylene even after they are harvested, and are exposed to external sources of ethylene, confined storage areas, refrigerators and freezers are full of the deadly gas. You've seen the effects of ethylene gas damage many times: shrink (fresh produce and flower bulbs); russet spotting (leafy vegetables and eggplants); yellowing (cucumbers, broccoli and brussel sprouts); odor (garlic and onions); wilting (vegetables and cut flowers); scald and loss of crunch (apples); and rind breakdown (citrus). . Without a system to remove this ethylene gas, the optimum shelf life of your fruits and vegetables can be cut to only a few days! . Passing the Test Independent testing by the Department of Geology at the University of South Florida and Pearson Testing Laboratories, Inc. in Marietta, Ga., has demonstrated the FridgeBuddy's ability to absorb ethylene gas and moisture - and the effect that ability has on the shelf life of perishable food. More than 2,300 hours of testing at the University of South Florida determined the mineral Guerite - absorbs up to 5% of its weight in ethylene gas and up to 11% of its weight in water. This mineral is used in some food storage products to elongate the lifespan of foods. (MORE)
H_ ..... _H H_C=C_H In C 2 H 4 (ethane, ethene, ethylene) there is a double carbon bond between CH 2 structures.
The formula for ethylene is C 2 H 4 The carbons are linked by a double covalent bond: H 2 C=CH 2
The Ethelyn gas is produced by the fruits. If you keep your fruits in the refrigerator the Ethelyn gas will stay inside the fruit and will not be able to come out because it is hard for it yo expand so if you keep your fruits outside the refrigerator then your fruits will last longer.
The standard enthalpy change of vaporization of ethylene glycol is56.6 kJ / mol. The enthalpy change of fusion is 9.9 kJ / mol.
Get some zeolite and package it in sachetes orbaby food jars with holes in the lid, or round ceramic sachetteholders. Whatever you package it in should let air in so theethylene gas comes into contact with the zeolite. You can findzeolite in a lot of products that control odor. I found the mostine…xpensive product is the Gonzo Odor Eliminator bag. It's a netbag that contains zeolite. It has one pound of zeolite. It's soldonline and at Walmart and Home Depot. If you need a lot more than apound, you can probably find an industrial supplier online. I justuse mine for keeping fruit and veggies fresh. Also, exposure tosunlight renews the zeolites ability to absorb ethylene gas. Idon't know if this zeolite is OK to actually touch the produce.That's why I put it in something that lets the air in while keepinga barrier from the produce. (MORE)
Ethylene is a plant hormone that causes fruits to ripen. Unripened fruits can rot, so if ethylene caused fruit to rot, it should ripen them first. The cause of rotting fruit is most likely due to microorganisms, especially bacteria.
Ethene, but I don't know why. I looked it up in google; I typed 'IUPAC for ethylene'
ethylene gas is a gas that plants produce to help them grow and age faster sometimes too much ethylene gas can result to over ripening (rotting) to reduce over ripening, put your produce in a cold area such as the fridge because the cold slows down the production of ethylene gas
Every plant is sensitive to ethylene gas. Ethylene is emitted when damage is done to a plant. It stimulates repair or ripening so that reproduction can take place before it's too late. Bananas are an example of this ripening effect. Put green bananas beside ripe ones and the ethylene ripens the gree…n bananas faster than they would have ripened on the other side of the room. Ethylene ripens all fruit, tomatoes, pears etc. The same is true of flowers. (MORE)
from http://en.wikipedia.org/wiki/Ethylene#Effects_upon_humans :. "Depending on the concentration, ethylene gas can cause a pleasant odor, euphoria, nausea , hyperglycemia , a variety of psychological effects, blood pressure changes, hypoxia , loss of consciousness, or death.. Exposure at 37.…5% for 15 minutes may result in marked memory disturbances. Humans exposed to as much as 50% ethylene in air , whereby the oxygen availability is decreased to 10%, experience a complete loss of consciousness and may subsequently die due to hypoxia .". Keep in mind that anything, in a large enough dose, is harmful. (MORE)
NO! Ethylene glycol is deadly poisonous even in relatively small amounts. Ethylene glycol is not ethyl alcohol, which is the only alcohol humans (or animals) can safely drink.

The biosynthesis of ethylene starts with conversion of the amino acidmethionine to S-adenosyl-L-methionine (SAM, also called Adomet) by the enzyme Met Adenosyltransferase. SAM is then converted to 1-aminocyclopropane-1-carboxylic-acid (ACC) by the enzyme ACC synthase (ACS) ; the activity of ACS der…termines the rate of ethylene production, therefore regulation of this enzyme is key for the ethylene biosynthesis. The final step requires oxygen and involves the action of the enzyme ACC-oxidase (ACO), formerly known as the Ethylene Forming Enzyme (EFE). Source: wikipedia (MORE)
Ethylene glycol binds with water, so it can be rinsed and diluted. The primary danger is its sweet taste, so children and animals can eat it, and it is toxic.

An ethylene cracker is a petrochemical plant. Primarily it takes in a feed of gas hydrocarbons (dry gas, propane, butane) or kerosene (rarer). It then heats it up to about 900degrees to literally "crack" the molecules into smaller ones. After this heating, the product is a mixture of lots of differe…nt gases and some liquids. These are then separated (refined) into different products. The primary product is ethylene. Most ethylene crackers have a hydrogenation section. This is a series of reactors which hydrogenate (add hydrogen) any acetylene turning it into ethylene. This increases the ethylene yield. (MORE)
