Organic phosphorus derivative of 2,4-di-tert-butylphenol, production of organic phosphorus derivative of 4,4-dihalomagnesium compound of biphenyl and use of the organic phosphorus derivative in stabilization of plastic, especially, polyolefin molding composition |
| abstract |
PURPOSE: To simply obtain the title deriv. useful for stabilizing plastic, especially, a polyolefin molding compsn. in high purity by reacting a specific Grignard compd. with specific ester-chloride. n CONSTITUTION: 4,4'-Dihalobiphenyl containing halogen having an atomic wt. of at least 35 (i) is reacted with Mg under a Grignard condition (ii) to obtain a corresponding Grignard compd. A and the component A is reacted with a phosphorous-bis-(2,4-di-t-butylphenyl)-ester-chloride represented by formula I (B) to obtain a compsn. wherein at least 50 wt.% of P is bonded in a form of tetrakis-(2,4-di-t-butylphenyl)-4,4'-biphenylene-diphosphonite represented by formula II. It is pref. to react the component (i) with the finely divided component (ii) in the absence of an azeotropic agent. n COPYRIGHT: (C)1990,JPO |
