DEHA DlETHY LHYDROXYLAMINE, 85% (C2HshNOH Diethylhydroxylamine, originally developed for use in the synthetic rubber industry, i s currently creating much interest in other areas because of its combination of stability, ease of handling, low toxicity and unusual chemical properties. Applications of DEHA as a stopping agent in emulsion polymerization, as an inhibitor of popcorn polymers in SBR manufacture, and as a stabilizing agent for styrene monomer have been reported. Its use as a developer component in newer photographic processes has appeared in patents. The properties of corrosion inhibition, retardation of paint skinning, and antioxidant effect on fats and oils are attributed to the uptake of molecular oxygen by DEHA. Data sheet and samples available on request. 0

Diethylhydroxylamine is another example of Pennsalt’s expanding capabilities in organic nitrogen chemistry. If you are interested in nitrogen chemicals, discuss your requirements with Pennsalt.

but we keep sneaking in little improvements.

The important changes are on the inside. We've done things, for example, to the rotating hammers that perform the particle size reduction. These impact elements last longer today because the striking edges are made from the hardest, most abrasive-resistant alloy available. New screens and liners have been developed to handle a growing range of processed materials. Up-to-date bearing design provides smooth, accurate operation. A lot of little things , but they add up to more precise particle control and efficient, 'round-the-clock operation at high capacity requirements. For 100% satisfaction with your granular or fine grinds, stick with the accepted industry standard, the job-designed MIKRO-PULVERIZER. It isn't what it used to be, by a long shot. We'll be glad to send details in Bulletin MP-1.
