Embodiment 1
[0037] Put 155g of 2-mercaptobenzoic acid, 130g of isooctyl alcohol, and 1.6g of concentrated sulfuric acid into the reactor, stir, raise the temperature to 105°C, and continue the reaction for 3.5 hours at a vacuum of -0.06MPa, remove the generated water, and then wash with water to remove the concentrated Sulfuric acid, dehydration to obtain isooctyl mercaptobenzoate; mix the intermediate product of the above reaction with 165g butanediol methyl ether at 60-65°C for 30 minutes, then add 95g of barium hydroxide, heat up to 105°C, and react for 3.5 hour, dehydrated, filtered to obtain barium isooctyl mercaptobenzoate, and the content of barium was 13.50% after determination.
Embodiment 2
[0039] Put 155g of 2-mercaptobenzoic acid, 330g of behenyl alcohol (C22 alcohol), and 2.0g of concentrated sulfuric acid into the reactor, stir, heat up to 115°C, and continue the reaction for 2.5 hours at a vacuum of -0.09MPa to remove the generated water. Then wash with water to remove concentrated sulfuric acid, and dehydrate to obtain behenyl mercaptobenzoate; mix the intermediate product of the above reaction with 50g of butanediol methyl ether at 60-65°C for 40 minutes, then add 97g of barium hydroxide, and heat up to 115 ℃, reacted for 2.5 hours, dehydrated, and filtered to obtain barium behenyl mercaptobenzoate, and the content of barium was 11.86% after determination.
Embodiment 3
[0041] Put 155g of 2-mercaptobenzoic acid, 130g of high-carbon fatty alcohol (C12-14 alcohol), and 2.4g of concentrated sulfuric acid into the reactor, stir, heat up to 110°C, and continue the reaction for 3.0 hours at a vacuum of -0.075MPa, remove The generated water is then washed with water to remove concentrated sulfuric acid, and dehydrated to obtain a high-carbon fatty alcohol ester of mercaptobenzoic acid; the intermediate product of the above reaction is mixed with 100 g of butanediol methyl ether at 60-65 ° C for 40 minutes, and then put into hydrogen oxidation 97g of barium was heated up to 105° C., reacted for 3.5 hours, dehydrated, and filtered to obtain barium mercaptobenzoic acid high-carbon fatty alcohol ester. After measuring, the barium content was 13.18%.
