| titleOfInvention | METHOD OF OBTAINING 0,0'-DI- (ALKYLPHENYL) DITIOPHOSPHORIC ACIDS |
| abstract | The invention relates to the chemistry of organophosphorus compounds, in particular the production of O, O 'di- (alkylphenyl) dithiophosphoric acids, which can be used in the production of additives to lubricants. The goal is to reduce the duration of the process and improve the quality of the target products. The preparation is carried out by the reaction of alkylphenols with five-sulfur phosphorus at 130–155 ° C in the presence of a catalyst. It is used as a carboxylic or organosubstituted mineral acid in the amount of 0.5–11.0 wt.%, Counting on alkylphenol. It is preferable to use O, O 'dithiophosphoric diester as a catalyst. The method provides a reduction in process time to 0.5 - 3.5 h, while achieving a high (95.5 - 100%) conversion of the starting alkylphenol. 1 h. the item f., 1 tab. |
