on some chlorotoluenes high-purity muriatic acid phenylneopentyl phosphite
NEED A NITROBENZOYL GROUP? For a practical way of putting nitro-benzoyl groups into organic compounds, we suggest use of two highly pure isomers of nitrobenzoyl chloride.
Hooker ρατα-nitrobenzoyl chloride usually assays higher than our specification of 98% minimum by weight.
These yellow, crystalline flakes are used to prepare azo and stilbene dyes and such pharmaceuticals as folic acid and procaine hydrochloride.
Our meta-nitrobenzoyl chloride is a mixture of isomers containing mostly meta-, never less than 92%. It assays a minimum 96% total nitrobenzoyl chlorides. It is used as an intermediate in making dyes and pharmaceuticals.
For more complete > description and information on specifications and typical physical properties, please check and mail the coupon.
SOLVING AN OFF-COLOR PROBLEM FOR HCI USERS If you're making a product that should be white but comes out yellow, maybe your muriatic acid has too high a level of iron or sulfate.
A switch to Hooker® White grade should clear up the trouble for you in a hurry.
One of the purest muriatic acids you can buy anywhere in volume, it contains maximums of 0.0001% iron, 0.003% sulfates, 0.0002% organic matter and is free of arsenic and free chlorine.
Y o u c a n o r d e r i t i n t h r e e strengths: 18°, 20° and 22° Baume.
The specs on our commercial grade are only slightly less rigid— 0.0005% iron, 0.003% sulfates, a trace of free chlorine, no arsenic.

PHENYLNEOPENTYL PHOSPHITE This is the structure of phenylneopentyl phosphite, a new composition of matter under our U. S. Patent 2,834,798. This new product is an inviting intermediate for synthesis with such common reagents as organic halides, halogen acids and organic acids.
It is a potential stabilizer of plastics and fluid systems, and of interest as a reactive intermediate in polymerization reactions.
You can open the cycloalkyl ring, if you like, through Arbuzov-type reactions. The phenyl group is removable by hydrolysis, giving you neopentyl phosphite.
Phenylneopentyl phosphite is a water-white liquid with a typical boiling point of 138-140°C at 10 mm and a melting point of 19°C. We distill it to > 98% purity.
You can buy it in semicommer-cial quantities. If you'd like to get more information, just check the coupon.
