red-purple deliquescent crystals. Soluble in water, acid and ethanol. Dark red, monoclinic prismatic crystals. Microstrip acetic acid odor. Soluble in water, ethanol, dilute acid and amyl acetate. The pH of the 0. 2mol solution was 6.8. The relative density was 1. 705. Refractive index 1-542. There is a potential for cancer. Not easy to burn. By high heat decomposition of toxic gases.
with metal cobalt or cobalt oxide as raw materials, and nitric acid or sulfuric acid reaction to produce cobalt nitrate or cobalt sulfate, and then add acetic acid acidification, evaporation, crystallization, separation, drying, cobalt hydroxide or cobalt carbonate may also be obtained by reaction with excess acetic acid.
The catalyst used in the transesterification reaction is about 0. o1% to 0. o5% in the production of polyester resin. It is also used for the preparation of paint and coating drying agent, printing and dyeing mordant, glass fiber reinforced plastic curing accelerator, etc.
