Abstract: A method for making a hindered phenolic antioxidant based on Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate uses a methanol solution containing alkali metal methoxide as a catalyst solution, wherein the catalyst solution is filtered with a filter device with a filter pore diameter of less than 50 μm to remove insoluble matters therefrom before used in a transesterification process where methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate and 1-Octadecanol are taken as reactants to obtain a crude product of Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate having high conversion rate and low color, and the crude product further undergoes a purification process for crystallization, filtering and drying to obtain a product of Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate having high purity and low color.

Abstract: A hydrogenation process for hydrogenating bisphenol-A-based epoxy resin under low-temperature, low-pressure conditions includes using a hydrogenation reactor that has a gas-distributing agitator functional to introduce and exhaust hydrogen gas and stir liquid reactant, so that hydrogen gas introduced into the hydrogenation reactor can be evenly distributed into a liquid reactant placed into the hydrogenation reactor to make the liquid reactant contain a high level of dissolved hydrogen, which not only enhances activity of an involved hydrogenation catalyst and accelerates hydrogenation reaction, but also allows hydrogenation reaction to be performed in a low-temperature, low-pressure environment. The hydrogenation process improve yield of the hydrogenated bisphenol-A-based epoxy resin to 99.0-99.9%, while significantly reducing building and maintaining costs for the hydrogenation reactor, thus being an economic process.

Abstract: A method for preparing esters of cyclohexane polycarboxylic acids from esters of benzene polycarboxylic acids makes improvement to hydrogenation of esters of benzene polycarboxylic acids by using a reaction tank having a gas-introducing mixer capable of extracting and exhausting air and stirring to hydrogenate an ester of a benzene polycarboxylic acids into an ester of a cyclohexane polycarboxylic acid in the presence of a hydrogenation catalyst; resulted in that the method advantageously minimizes the operational pressure for hydrogenating esters of benzene polycarboxylic acids and significantly lowers the reaction temperature for hydrogenation while effectively improving the yield of esters of cyclohexane polycarboxylic acids made from the esters of the benzene polycarboxylic acids.
