Is glycerol positive for acrolein test?
yes
Will waxes give a positive result toward acrolein test?
ewan
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.
What is the significance of the 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

If it is mixed well.

What is Responsible for the characteristic odor of acrolein test?
help!i need a answer.:(
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
If lecithin still had all its ester linkages would you get a positive acrolein test?
yes...ask Dr. Stinson..and stop trying to get answers of the internet, he said we should do it unaided
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.
