but in my school lab, we don't have a GC or NMR. is there other simple test for present of methanol?

i am carrying one experiment on the decomposition of sweetener-Aspartame under acidic condition which will give out methanol is it easy to test for the present of methanol there by adding potassium permanganate?

any simple test to test for the present of methanol?

then why i can find the detail that some sweeteners are about 100times sweetness of sucrose, and some is about 1000 times. how can the scientist get this kind of value?

how about measure the sweetness of the sweetener? i doesn't contain any sugar.

any people can help on this problem?

any testing solution or other method that can test for the sweetness of some substance. I mean except using the mouth.

i see, i am just a high school student and this experiment will be held in the school lab.

if i conduct the experiment of thermal stability, any special apparatus need to use?

i see thanks do u still have any other suggestion?

i need to conduct a project on sweetener, any interesting experiments can be conduct on this topics??

can we simply use growing sprint?

i see. I get your point, thanks~!

that mean the reason for these are caused by diople moment and H-bonding?

3-Pentanone, also known as diethyl ketone, is a colorless liquid ketone with an odor like that of acetone. Its formula is C5H10O. Its boiling point is 215°F (101.7°C), and its freezing point is -44°F (-44.2°C). Two other ketones which are isomers of 3-pentanone are 2-pentanone and methyl...
