dehydrant การใช้

Experimental study on enhanced deaquation process for extra - heavy crude oil using dehydrant
Using niobic acid as catalyst , cyclohexane as dehydrant , benzyl propionate was synthesized based on propionic acid and benzyl alcohol
It is widely used in pharmaceutical , perfumery , leather and chemical industry ; as compound cyclizing agent in organic synthesis , acidifier and dehydrant ; as substitute of ortho - phosphoric acid
With phosphato - tungstic acid as catalyst and phosphoric acid as dehydrant , n - phenylmaleimide was prepared from aniline and maleic anhydride by two - step method . the yield was 88 . 7 % and the purity was 98 . 2 %
Phosphorus pentoxide is usual material and reagent in chemical industry , this product is widely used in the industries of medicine , coating auxiliaries , printing and dyeing auxiliaries , anti static additive , titanate coupling agent , phosphorus oxychloride , chemical . mainly used in producing high purity phosphoric acid , used as desiccant of gas and liquid , dehydrant of organic synthesis
