Raw Materials

Sulfuric acid hydrazine hydrate Benzophenone

Reference Information

application	dibenzophenone hydrazone is an important raw material for the synthesis of photosensitive materials, fragrances and medicines, and is an intermediate for ultraviolet absorbers, organic pigments and pesticides.
Preparation	CN200610051887 provides a simple operation, mild reaction conditions, high yield, easy availability of raw materials, low cost, and low environmental pollution. A method for synthesizing dibenzophenone hydrazone with lower concentration of hydrazine hydrate as raw material. The technical scheme adopted by the invention is as follows: a synthesis method of benzophenone hydrazone, in which benzophenone and hydrazine hydrate are reacted in an ionic liquid at 80-140 ℃ for 0.5-6h, and the reaction product is post-treated to obtain the dibenzophenone hydrazone shown, and the reaction formula is as follows:
Use	Used as organic pigment and pharmaceutical intermediate Used in organic synthesis.
production method	anhydrous ethanol solution of benzophenone is refluxed with anhydrous hydrazine for 10h, and dibenzophenone hydrazone is precipitated by cooling, with a yield of 87%.
