Can Methanol be mixed with Antifreeze?
Yes, methanol can be mixed with antifreeze. Methanol is sometimes added to antifreeze solutions to decrease the freezing point and improve the efficiency of the antifreeze. However, it is important to follow the manufacturer's recommendations and safety guidelines when mixing methanol with antifreeze.
Does all gas contain methanol?
Not all gasolines contain methanol. Methanol is an oxygenate and is distilled. When Methanol is used all Major Manufacturers discourage mixtures above 10%. The other Oxygenates used are: Ethanol which is produced by fermentation and when used the Major manufaturers discourage a mix greater than 10%. Methyl Tertiary Butyl Ether (MTBE) which is also a distilled product and when used The Major manufacturers discourage a mix of more than 15%. in many states these are only used during the winter months but there are some moajor metropolitian areas in the US that mandate that only oxygenated fules can be sold year round.
How do you calculate rate of evaporation of methanol?
Maybe I can help you. My experience was with ethanol. It may work with mehanol if it has a distinctive smell like ethanol does. I needed to know how much evaporated off the floor of a room so I could ventilate the room to prevent an explosive condition. I bought a bottle of 100 proof vodka (50% ethanol). I got a stop watch and a graduated cylinder. I carfully measured a specific amount. I found a surface that was the temperature and mass desired to simulate my desired conditions. In my case I used a parking lot surface similar to the highest temperature of the concrete room floor. I pored the ethanol on the parking lot and started my stop watch. Every 10 seconds I put my nose to the wet puddle of ethanol. When I did not smell the ethanol, I stopped the watch. I had my number. There is an equation in some thermodynamics books that uses the vapor pressure, the ambient partial pressure, molecular weight, and temperature to calculate the evaporation rate.
Does BP have ethanol?
Yes, BP does offer ethanol-blended fuels at some of its gas stations. BP sells gasoline that contains up to 10% ethanol (E10) at certain locations.
How does ethanol counteract the poisonous effects of methanol?
Most of the toxic effects of methanol [H3C-OH], are from the first metabolite, formaldehyde [ H2C=O], which occurs when the enzyme Alcohol Dehydrogenase (ADH) oxidizes methanol into formaldehyde and the hemiacetal [CH(OH)2] - the later spontaneously forms formaldehyde in the presence of water. There are 6 subtypes of ADH in humans, which vary based on race and genetics, but they all have a preferred substrate, ethanol, when compared to methanol.When ethanol is given to someone who has consumed methanol, the active site of the enzyme ADH fits ethanol [CH3CH2OH] better than methanol [CH3OH]; the ethanol gets metabolized more often than the methanol. By occupying the active site on the enzyme with ethanol, the methanol is metabolized more slowly into the far more toxic metabolite, formaldehyde, than it would be if ethanol were not present. This gives the body a smaller amount of formaldehyde to deal with at any given time, and the toxic effects are more easily contained. The toxic effects of the smaller amount of formaldehyde do not cause irreversible damage because the cells that were the most sensitive to formaldehyde (the liver, the kidneys and the retinae) do not get as much damage and can repair themselves up to a point.Now this is an important point as to why this procedure works: Most drugs follow first order kinetics, K1, meaning that the enzyme detoxifies a constant percentage of the drug in a certain period of time (the time for 50% of a drug to be metabolized is called the half-life or t1/2 ). But ethanol and methanol follow zero order kinetics(K0), meaning a certain amount (weight or volume) of the drug is metabolized in a fixed time, for ethanol, it is about 1 oz per hour.For Advanced students who are interested in Enzymology, Pharmaceutical Sciences or Toxicology,, here are some additional pieces of information:A)Now, realistically, all drugs follow first order kinetics K1 within a certain range, and zero order kinetics K0 when the enzyme is saturated (meaning there is far too much of the drug around and far too little enzyme, so that even if every active site on every enzyme were occupied at one time, there would still be lots of drug left over.) Most drugs have a physiologic/pharmacologic effect in the microgram -- gram range; alcohol is the exception. When alcohol gets metabolized below about one gram, we start to see first order kinetics K1 instead of zero order kinetics K0. I have been asked in class many times if there are any enzymes that follow K2 or second order kinetics, like when a co-factor such as a vitamin is involved (Vitamin A in the Krebs Cycle for Acetyl-CoA). The answer is emphatically, NO. The probability of three molecules meeting together at random in the correct orientation approaches zero. It would be such a rare event that you could not sustain life if this were required. The binding of a co-factor or other component to an enzyme is a separate step, and is unrelated to t1/2 because there is so much co-factor around compared to the drug, that for all intensive purposes, you can assume, under normal conditions, that the enzyme and co-factor are always bound together.B)Ethanol is oxidized by ADH into acetaldehyde and ethylene glycol, both of which are far less toxic than formaldehyde (not non-toxic, however, just less toxic; all three compounds are relatively toxic with formaldehyde>ethylene glycol>acetaldehyde.) The drug Antabuse(disulfiram), inhibits the enzyme Aldehyde Dehydrogenase, which converts acetaldehyde into acetate or acetic acid (3% (v/v) acetic acid in water is vinegar). It is acetaldehyde that is partly responsible for hangovers and makes most people feel bad in the ethanol metabolism chain, not ethanol itself or acetic acid.MobiusDick
Which one is used as antifreeze methanol or ethanol?
Both methanol and ethanol can be used as antifreeze, but methanol is more commonly used due to its lower freezing point and better compatibility with engine materials. However, ethanol is also used as an antifreeze in some applications, particularly in countries where it is more readily available.
What are the example of cosolvent?
The best examples for Cosolvents are Methanol & Ethanol.Infact ,Methanol is not miscible with N-Hexane ,but if you add some amount of ethanol methanol and N-hexane will be completely miscible.

What is the chemical name for wood alcohol?
'Alcohol' , chemically, is a collective name for a list of substances with the '-OH' functional group. The following are some alcohols.;- Methanol, Ethanol, Propanol Butanol Pentanol Hexanol et. seq. There are many more alcohols. I suspect that you are thinking of the 'alcohol' that is in beers, wines and spirits.. The chemical formula for ethanol is 'CH3CH2OH'. That alcohol is ethanol, archaically, 'ethyl alcohol'. The other alcohols listed above cannot be consumed by humans.
Can Methanol be mixed with Antifreeze?
Yes, methanol can be mixed with antifreeze. Methanol is sometimes added to antifreeze solutions to decrease the freezing point and improve the efficiency of the antifreeze. However, it is important to follow the manufacturer's recommendations and safety guidelines when mixing methanol with antifreeze.
Can you give few examples of low cost fuels?
some of the low cost fuels are bio ethanol,bio methanol,cellulose bio mass etc.
Is methylated spirits polar or non polar?
Methylated spirits, primarily composed of ethanol and sometimes containing methanol and other additives, are generally polar. The presence of the hydroxyl (-OH) group in ethanol contributes to its polarity, allowing it to interact with other polar substances. However, the presence of non-polar additives can introduce some non-polar characteristics, but overall, methylated spirits are considered predominantly polar.
What is wood alcohol for?
Wood alșcohol isa very old name for methanol -CH3OH. Some applications areȘ- solvent- denaturant for ethanol- antifreezing agent- fuel
Why is correction fluid flammable?
Although most correction fluids you can buy today are classed as non-flammable, some contain toluene, methanol and/or ethanol which are all flammable.
What is rubbing acohol?
It's either isopropanol or ethanol in varying concentrations. It always has a poison added, either benzene, methanol or some other adulterant to make it impossible to drink. This process causes the alcohol to be called denatured alcohol.
Why is that another solvent can be used instead of ethanol?
Depends on what you are trying to dissolve. Some other industrial solvents include isopropyl alcohol, methanol, toluene, acetone and methyl ethyl ketone.
Why is using ethanol and methanol bad in terms of food production?
Ethanol and methanol is made from fermented plants, sometimes the same plants that humans can eat. The fields where these plants to make ethanol/methanol are grown could otherwise have been used to grow food for humans on. So to exaggerate a little, we're taking food and turning it into fuel. Now, if we already have enough food and farm land, this doesn't mean much. but if we need to clear more ground for fuel farming, then there's an environmental impact of that. If farmers start growing for fuel instead of for food, then food prices may rise. This can be economically bad ffor some people.
