Title:
PREPARATION OF ANTHRAQUINONE
Document Type and Number:
Japanese Patent JPS59116245
Kind Code:
A
Abstract:
PURPOSE: To prepare anthraquinone useful as an intermediate for synthesizing dye, etc. or an auxiliary for pulp digesting without hardly causing by-products, by oxidizing catalytically an anthracene derivative replaced with an alkyl in a gaseous phase, using a lead compound as a catalyst.
CONSTITUTION: In preparing anthraquinone by oxidizing an anthracene derivative shown by the formula (R is any substituent group of 1W3C alkyl; m and n are 0W4) with molecular oxygen catalytically in a gaseous phase, a lead-containing compound (e.g., metal lead, lead sulfide, lead oxide, lead halide, lead nitrate, lead acetate, etc.) is used as a catalyst. One or more of Na, K, rare earth metals, etc. as a cocatalyst may be added to the lead compound.
