SULPHUR-CONTAINING ESTERS OF PHOSPHORIC ACID AND PHOSPHOROUS ACID, PROCESSES FOR THEIR PRODUCTION AND USE THEREOF |
摘要 |
<p>Trithio- and tetrathiophosphates with mercaptocarboxylic acid derivatives are preeminently suitable as extreme pressure additives for lubricants. They reduce signs of wear and have no or only an insignificant corrosive action on the parts to be protected. They are obtained in high yields, shorter reaction times and relatively free from by-products via the trithiophosphites by reaction of phosphorus trihalides with mercaptans in the presence of a catalyst and subsequent oxidation with sulphur or an oxygen donor.</p> |
