| titleOfInvention | Antioxidant for rubber of emulsion polymerization and method for its preparing |
| abstract | FIELD: chemical technology. n SUBSTANCE: invention relates to preparing antioxidants of phenolic type. Method involves using alkylation products of mixture of para- and ortho-isomers of isononylphenol with isobutylene as an antioxidant. Alkylation reaction is carried out at 40-120°C and 0.02-0.4 MPa in the presence of acid catalyst in batch and continuous feeding isobutylene to reactor unit providing maintaining isobutylene concentration in reaction mass 0.8 mole/l, not above, and the total amount of isobutylene feeding to alkylation 1.82-2.0 mole per 1 mole parent alkylphenols. Method provides preparing antioxidant showing good technological properties and high effectiveness of protective effect for rubbers of emulsion polymerization and rubbers based on thereof, and simple method for its synthesis also. n EFFECT: improved method for preparing. n 6 cl, 3 tbl, 7 ex |
