Polymerized Rosin, Rosin Methyl Ester And Terpene-phenolic Resin Catalyzed By Solid Acid

Rosin is contained in the pine resin（resin） processing for a class of non volatile acid resin solution complexes. It is one of the valuable renewable resources. It was found that rosin can be used to replace partial disposable resources. However, due to the existence of carboxyl and double bonds in the molecular structure of rosin, it has the defects such as brittle, non-aging and so on, which has restricted its application in many industrial sectors. Therefore, it is an effective means to increase the practical value of rosin by means of esterification or polymerization, reducing the number of carboxyl group and double bond. In addition to the non volatile rosin addition to another part of the mixed group of volatile terpenes, are known as turpentine. Because turpentine is the main component of structure of double bond functional group and ring functional groups of α-pinene and β-pinene, its application is mainly polymerization chemical reaction. Terpene phenolic resin is obtained by polymerization of alpha pinene and phenol. This is the modified product of renewable resources, to alleviate a current resource depletion of industrial products.The polymerized rosin was usually catalyzed by sulphuric acid and zinc chloride some seriously problems exit in the production process such as production equipment corrosion and environmental pollution. Traditional industrial production was by using sulfuric acid or p-toluene sulfonic acid as catalyst to methyl ester of rosin, which had high reaction temperature（250³00 ℃）, reaction time long（7¹1 h） and requirements. The production process of the synthesis of terpene phenolic resin, was that the AlCl3 catalyst, had the same defects, such as high cost of industrial production, serious environmental pollution, catalyst recovery and poor reuse performance.The main research of this paper was as followed: preparation of SO42-/Mx Oy type solid super acid by precipitation impregnation method; catalytic synthesis of polymerized rosin, rosin methyl ester and terpene phenolic resin by SO42-/MxOy type solid super acid. The characteristics of organic synthesis in SO42-/MxOy solid super acid as catalyst had green chemical and clean production. Therefore, the catalyst had broad application prospects and academic value.The main achievements of the paper: the main research of SO42-/TiO2/La3+ solid super acid catalyzed synthesis of polymerized rosin. The effects of reaction time, catalyst dosage and reaction temperature on the reaction were investigated. The better technological conditions were obtained and the reproducibility was good.

SO42-/TiO2-Zr O2/La3+ solid super acid catalyzed synthesis of rosin methyl ester. The effects of reaction time, reaction temperature, catalyst amount, acid alcohol molar ratio on reaction were investigated in detail. And the better technological conditions were obtained. The preparation conditions of the catalyst were investigated. SO42-/TiO2-Al2O3/La3+ solid super acid catalyzed synthesis of terpene phenolic resin. The effects of turpentine oil and phenol molar ratio, catalyst dosage, reaction time, stirring speed on the performance of terpene phenolic resin were investigated in detail.The SO₄^2-/M_xO_y type solid super acid was used to replace the traditional catalyst, which mainly overcomeed the defects of the corrosion equipment, the pollution environment, the difficult recovery of the catalyst and the difficult separation of the catalyst.
