Abstract:
using chloroacetic acid and isooctyl alcohol as raw materials, solid superacid as catalyst, under the condition of reduced pressure synthesis of chloroacetic acid isooctyl ester; Chloroacetic acid isooctyl Ester and sodium thiosulfate in PTC (phase transfer catalyst, the same below) under the action of the formation of Bunte salt, and then by acid hydrolysis, reduction, the formation of isooctyl mercaptoacetate. The effects of various factors on the product yield were investigated, and the optimum process was obtained as follows: the ratio of isooctanol to chloroacetic acid was 1.0, and the amount of solid superacid catalyst SA was 0.6% of the total mass of the reactants, the reaction time was 2.5~3 h, the ratio of isooctyl chloroacetate to sodium thiosulfate was 1.0 ∶ 1.0, the amount of sulfuric acid was 10% of the total mass of the reactants, and the reduction time was 60 min, the amount of zinc powder accounted for 2.0% of the total mass of the reactants. Under these conditions, the total yield of the product was more than 95%, and the purity of the refined product w (isooctyl mercaptoacetate) was more than 99%.

Abstract:
isooctyl mercaptoacetate was synthesized by esterification of mercaptoacetic acid and isooctyl alcohol catalyzed by Heteropoly acid HPW12,HPMo12 and α-HSiW11 immobilized on activated carbon as the catalyst, and the yield was about 95%; the factors affecting the reaction were discussed. The product was confirmed by boiling point, refractive index, IR,^ 1HNMR. The synthesis process parameters are as follows: the molar ratio of raw materials is, alcohol: acid = 1:1.2; The amount of water-carrying agent is 1.5 times that of acid; The amount of catalyst is 0.8% of acid; reaction temperature 125~130 ℃; Reaction time is 3H, the method has high catalytic activity and selectivity, synthesis process

Abstract:
The invention relates to a treatment method of mercaptoacetic acid isooctyl ester production wastewater, specifically: When the wastewater is treated, a part of organic matter in the wastewater is recovered by a self-extraction method, if the wastewater is acidic and needs to be neutralized, then part of COD and suspended solids in the wastewater are removed by hydrogen peroxide oxidation and air floatation respectively, and then the COD in the wastewater is further removed by activated carbon adsorption and decolorization, then, the inorganic salts were removed by distillation, and the wastewater finally reached the national discharge standard. The invention has an obvious treatment effect, and can make the esterification wastewater in the mercapto ester production wastewater, the mercapto wastewater and the reduction wastewater reach the national discharge standard, also has a simple process and easy to promote the effect.
