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.

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 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.
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 does Acrolein do to your body?
acrolein is in cigarettes
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.
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

Glycerol reacts with khso4 to form acrolein?
KHSO4 is a dehydrating agent for glycerol. On heating it gives ACROLEIN. I'll try to show it hereCH2OH-CH(OH)-CH2OH ----KHSO4 (-2H2O)----> CH2=C=CH-OH ----Tautomerize----> CH2=CH-CH=O (Acrolein also called acraldehyde)
What is the significance of the acrolein test?
