Abstract

Abstract:

　 The substitute for the Carnauba wax was synthesized by catalytic oxidation of paraffin and microcrystalline under acidic catalyst and then using physical blending method. The effects of different factors on the reaction were discussed by or thogonal experiment method. The optimum technological condition is obtained:the mass ratio of mix ed paraffin and micro crystalline is 4 ∶1, mass fr action of catalyst is 1. 0 %, mass fraction of promoter is 1. 6 %, reaction time is 8 h, air flow rate is 1. 25 m3 /h , reaction temperature is 170 ℃. After physical blending , acid number of the product is 12. 93 mg(KOH) /g , saponification number is 82. 71 mg(KOH) /g , index of refraction(75 ℃) is 1. 445 2, melting point is 82. 1 ℃. The product is compared with natural carnauba wax , their characters are similar.
