The acrolein test tests for the presence of glycerin or fats. There is no general equation for it, although the sample is heated with potassium bisulfate and if acrolein is released, the test is positive.

∙ 14y agoThe importance of the acrolein test is to test whether glycerol (the alcohol found in triacylglycerol) is present in a compound. Glycerol and potassium bisulphate will form a compound called Acrolein, which has almost the same smell of burnt grease or motor oil

∙ 15y agoThe principle behind the acrolein test is a specific chemical reaction. This reaction is utilized to determine the presence of glycerin in a fat. By heating the fat sample in the presence of potassium bisulfate (KHSO4), which acts as a dehydrating agent, acrolein (C3H4O, or CH2=CH-CHO) is formed and can easily be detected by its odor. Whenever fat is heated in the presence of a dehydrating agent, the fat molecule will shed its glycerol in the form of the unsaturated aldehyde - acrolein. Acrolein smells like burned grease, and this toxic chemical was used in the first World War as a chemical weapon. Even in small concentrations, exposure irritates the mucous membranes and causes the eyes to tear up. It can incapacitate individuals very quickly at levels of only a few parts per million. Wikipedia has more information on acrolein, and a link is provided.

The result of Acrolein Test?
Acrolein test is a test for the presence ofglycerin or fats. A sample is heated with potassium bisulfate, and acrolein is released if the test is positive.[8] When a fat is heated strongly in the presence of a dehydrating agent such asKHSO4, the glycerol portion of the molecule is dehydrated to form the unsaturated aldehyde, acrolein (CH2=CH-CHO), which has the peculiar odor of burnt grease.
Is glycerol positive for acrolein test?
yes
Lipid that are positive to acrolein test?
Glycerin
What is the Balance equation for acrolein test?
The acrolein test tests for the presence of glycerin or fats. There is no general equation for it, although the sample is heated with potassium bisulfate and if acrolein is released, the test is positive.

Why acrolein is a general test for fats?
Because when a fat is heated strongly in the presence of a dehydrating agent such as KHSO4, the glycerol portion of the molecule is dehydrated to form the unsaturated aldehyde, acrolein (CH2=CH-CHO), which has the peculiar odor of burnt grease. A sample is heated with potassium bisulfate, and acrolein is released if the test is positive. That's why Acrolein test is a test for the presence of glycerin or fats. source from the page of: http://en.wikipedia.org/wiki/Acrolein

What is the role of KHSO4 in the acrolein test?
When lipids are heated in the presence of potassium bisulfate (KHSO4), a characteristic burned fat odor of acrolein is produced. :D

What is the odor of coconut oil in acrolein test?
The smell of acrolein is that of burnt fat (when cooking oil is heated to its smoke point). This is caused by the breaking down of glycerol into acrolein when burning (or overheating, pyrolizing) fat.
Can you use sodium bisulfide instead of potassium bisulfide in acrolein test?
The Acrolein Test uses Potassium BiSulfate (KHSO4), not Potassium Bisulfide (KHS). It is the BiSulfate ion that does the work, so the Sodium salt should work. You should always test your reagents with glycerine.
What does Acrolein do to your body?

What is the acrolein in lipids?
An acrolein is in organic chemistry, acrolein or propenal is the simplest unsaturated aldehyde. Acrolein is described as having a piercing, disagreeable, acrid smell similar to that of burning fat. Skin exposure to acrolein causes serious damage. Acrolein concentrations of 2 ppm are immediately dangerous to life. Acrolein may be easily produced by the action of approximately 1 part sodium bisulfate on 3 parts glycerine by weight. Acrolein is such a severe pulmonary irritant and lacrimating agent that it has been used as a chemical weapon during World War I. It is, however, not outlawed by the Chemical Weapons Convention. When glycerol is heated to 280 °C, it decomposes into acrolein. Acrolein tends to polymerize when left at room temperature, leaving a gummy yellowish residue with a putrid odor. Acrolein is also a metabolite of the chemotherapy drug cyclophosphamide, and is associated with hemorrhagic cystitis.
