A new technology for simultaneous isomerization and dimerization of resin acids with HCl-ZnCl2 as catalyst has been developed. Factors influencing the process and the optimum conditions were investigated. It is confirmed that the technology has good controllability and stability. The product of 140 polyrosin contains about 60% dimers or more. On the other hand, HC1 not only possesses the ability of isomerization, decreasing the activation energy of the reaction, but also displays actively in the process, such...

A new technology for simultaneous isomerization and dimerization of resin acids with HCl-ZnCl2 as catalyst has been developed. Factors influencing the process and the optimum conditions were investigated. It is confirmed that the technology has good controllability and stability. The product of 140 polyrosin contains about 60% dimers or more. On the other hand, HC1 not only possesses the ability of isomerization, decreasing the activation energy of the reaction, but also displays actively in the process, such as increasing the content of dimers in the product, decreasing the decarboxylation, stabilizing the technological conditions and total yield.

本文开发了氯化氢-氯化锌使松香树脂酸的异构-二聚同时进行的新工艺,探讨了对工艺影响的因素,优选出工艺最佳条件,证实该工艺具有良好的可控性和稳定性,140标号的聚合松香其二聚体含量达60%或更高。氯化氢不仅有异构能力和活化反应体系,降低反应的活化能,并且在多方面有良好的促进作用,如:提高了产品的二聚体含量,减少了脱酸作用,稳定了工艺条件和产率。

It is generally agreed that the quality of the activated carbon depends mainly on the ratio of zinc chloride/wood flour and the activation temperature, but the effect of these two factors on the pore structure is not well known. We selected three levels of ZnCl2/wood ratios 2.5, 2.8, 3.1 and four activation temperatures: 380℃, 420℃, 460℃, 500℃ and prepared twelve batches of sample in different ZnCl2/wood ratios and activation temperatures. The pore-size distribution and pore volume of these carbon samples were...

It is generally agreed that the quality of the activated carbon depends mainly on the ratio of zinc chloride/wood flour and the activation temperature, but the effect of these two factors on the pore structure is not well known. We selected three levels of ZnCl2/wood ratios 2.5, 2.8, 3.1 and four activation temperatures: 380℃, 420℃, 460℃, 500℃ and prepared twelve batches of sample in different ZnCl2/wood ratios and activation temperatures. The pore-size distribution and pore volume of these carbon samples were determined . The experimental results indicated that the optimum ZnCl2/wood ratio and activation tem-perature were 2.8 and 420℃~460℃ respectively. It has shown that the most suitable conditions in manufacturing process can be chosen by the aid of pore volume and pore-size distribution determinations.

改变锌屑比和活化温度是影响氯化锌法制备糖用炭质量的主要因素。本文选用了锌屑比为2.5、2.8、3.1三个水平和活化湿度为380℃、420℃、460℃、500℃四个水平,仿照沙县活性炭厂的氯化锌法新工艺,制备了十二个炭样,并对它们进行了孔结构参数的测定,通过孔径分布曲线和微孔容含量分析,结果表明该工艺在锌屑比为2.8、活化温度为420℃—460℃下制备的炭样,其中孔、大孔的含量最多。本文研究进一步表明,可以通过对炭样进行孔结构分析的方法为探讨活性炭制备工艺的最佳条件,提供科学、有效的依据。
