BMK
I know Benzyl methyl ketone is used for amph/meth but what other uses industry wise does this get used for?
There is no information of what it oucld be used for or nothing.
Im thinking maybe a glue or an epoxy of some sort
There selling tons of it so there must be a good use

It has been used as a solvent in the past but its current status has resulted in it being replaced in all cases as far as I know.
It is still used as a synthon as it will condense quite readily to form phenyl substituted napthalenes, see here http://www.sciencedirect.com/science?_ob=ArticleURL&_udi... and lots of heterocycles.

From Ullmann Encyclopedia of Industrial Chemistry 6th ed.:
"Uses. 1-Phenyl-2-propanone is used as an intermediate for the synthesis of pharmaceuticals, e.g., Prenylamine, a coronary vasodilator (Hoechst)"
Merck-Index:
"Note: This is a controlled substance listed in the U.S. Code of Federal Regulations, Title 21 Part 1308.12 (1995). USE: In organic synthesis;
production of benzyl radicals by photolysis."
Roempp:
"Use: as intermediate for the production of pharmaceuticals, e.g. amphetamines. The isomer 1-phenyl-1-propanone is propiophenon"

One more reference found:
Merck-Index, 11 ed.:
"Use as prochiral ketone in enantioselective hydrosilation: H. Brenner et al., Ber. 117, 1330 (1984)"

As a solvent! No way. Who would you want that for a solvent? The benzylic hydrogens are too acidic and that makes it too reactive toward many
reagents, so it would be a terrible choice as a solvent for many reactions. Besides, solvents need to be simple to make from bulk materials and very
cheap. Therefore utmost its regioisomer propiophenone could have ever been used as a high boiling solvent.
Moving to beginnings...

You are thinking of solvents for chemical reactions.
Have a look at the solvent mixtures used in inks, paints, adhesives, resin mixtures, etc.
All sorts of amines, etc are used as modifiers often with water as a base solvent in modern emulsions.

Its main use as far as I know was perfume industry and amphetamine manufacturing. Yes it is legal for some people to produce amphetamines.

It was used as a cheap scent in soaps, polish, etc where it could also play a blending role.
Maybe it is still used for this purpose in some places?
I remember floor polish that was scented with nitrobenzene. I have not seen it for many years. Heavy exposure used to give you a stinking headache.

Nice posts was thinking of the idea of inks and so forth as at work that all we deal with and was willing to know of exposure to this is as harmfull
as it is to the other things they put in that nasty drgg

I received a sample of benzylethylketone and it seems promising as a perfumery intermediate. I suppose I'll some sort of condensation reaction maybe
with a CN ester. I'm requesting an article on it.
