| titleOfInvention | Preparation method of styrenated hindered phenol or styrenated phenol antioxidant product |
| abstract | The invention discloses a preparation method of a styrenated hindered phenol or styrenated phenol antioxidant product, belonging to the field of preparation process methods of polymer antioxidant products. The preparation method is characterized in that: o-tert-butyl phenol or phenol, p-cresol, o-cresol and m-cresol are used as raw materials, styrene is used as an alkylation reagent, an organic acid compound is used as a catalyst, a small amount of polymerization inhibitor is added, and the styrenated hindered phenol product or styrenated phenol product is prepared through catalytic alkylation reaction; a neutralizing and decolorizing agent is added to the styrenated product to deactivate the acidic catalyst and remove the coloring source material, thus obtaining a white-like or light yellow viscous liquid namely the styrenated phenol antioxidant product which has clear and transparent appearance, pH value of 6.5-7.5, storage stability and high use efficiency; and the styrenated phenol antioxidant product is free of water-soluble pollutants such as free phenol or methyl phenol, thereby solving the problem of environmental pollution caused by the use of the product in styrene butadiene rubber latex. |
