Production of Benzophenone Hydrazone
Preparation of benzophenone hydazone derivative, utilize benzophenone derivates, hydrazine hydrate reacts in the environment of acidic ionic liquid is prepared into benzophenone hydazone derivative, and by its by low-temperature plasma modified into the easily compound that is polymerize and triggered, the group to form bigger molecule by being acted on cross-linking agents again, pass through batch mixing together with other expanded material preparing raw materials again, mill, slice, sulfur foam, it is cooled and shaped, anti-aging expanded material needed for the technological process of processing is prepared into, avoid the problem of small molecule ultraviolet absorber easily volatilizees and migrated, not only there is the prerequisite softness of common expanded material, excellent feel, skid resistance, elasticity, compression performance is good, and also possess good anti-ultraviolet property.

Uses
Diphenyl-methanone Hydrazone is an intermediate used to synthesize Pseudobenztropine. It can also be used to prepare chiral paracyclophane-substituted triazolium salts as precursors for copper-triazolylidene-catalyzed asymmetrical boration of unsaturated N-acyloxazolidinones.
