BPS CAS NO.80-09-1

Chung Hwa Chemical Industrial Works, Ltd., is the first Sulfuric acid manufacture on Taiwan, also the Chemical manufacture over 60 years.

4,4'-dihydroxydiphenyl hydrazine is mainly used as a fixing agent.

Reacted from phenol and sulfuric acid.In addition, it can be used as a plating bath additive, a leather tanning agent, a dispersing agent for high-temperature dyeing of disperse dyes, a phenolic resin hardening accelerator, a resin flame retardant, and the like.

As a substitute for bisphenol A, it can be used as a raw material for polycarbonate, epoxy resin, polyester, phenolic resin, and as a raw material for polyfluorene or polyether oxime.

The product is also used in the manufacture of color photographic materials, contrast enhancers, thermosensitive recording materials (developers), daily surfactants, and high-efficiency deodorants.

Fixing agent A (foreign trade name Cibatex PA) can be obtained by using bisphenol S as a raw material.

It has excellent heat resistance, light resistance and oxidation resistance, and is a raw material for synthesizing polycarbonate, epoxy resin and polyfluorene and polyether oxime resin.

It can also synthesize dye fixing agent and leather tanning agent with bisphenol S, and can also be used as intermediates for electric additives, dyes, medicines, pesticides and additives.
