| titleOfInvention | Novel bio-based phosphite antioxidant and preparation method thereof |
| abstract | The invention discloses a novel bio-based phosphite antioxidant and a preparation method thereof, wherein the structural formula of a compound I is as follows: the novel bio-based phosphite antioxidant does not contain nonylphenol, and has the advantages of large molecular weight, environmental protection and safety. The invention provides a preparation method of the bio-based phosphite antioxidant, which comprises the steps of taking bio-based cardanol as a raw material, converting the cardanol into m-pentadecyl phenol through a hydrogenation reaction, and carrying out an esterification reaction on the m-pentadecyl phenol obtained through the reaction and phosphorus trichloride under the action of a catalyst and negative pressure to obtain the bio-based phosphite antioxidant. The antioxidant prepared by the method contains three P-O bonds, P shows positive trivalent, the steric hindrance is similar to TNPP, the hydrolytic stability of the antioxidant is equivalent to TNPP, and the antioxidant is good due to the large molecular weight and the good heat-resistant stability. |
