First, a lot of experiments about changing character on CaCO3 surface has been rearsched,example,fatty acid,pentaerythritol,rosin ester,cocoanut oil,rosin, pentaerythritol + rosin ester,glycerine + rosin ester ,cocoanut oil + oleic acid,titanate + fatty acid,cocoanut oil + fatty acid, and so on surface active agents. Among these surface active agents, cocoanut oil + oleic acid,and titanate+ fatty acid,and cocoanut oil + fatty acid are the best.

The optimum reaction conditions were as follows: rosin 5 g, m: in: m 1:2:2, palladium chloride 0.090 %, n: n1:10, hydrogen pressure 5 MPa, reaction temperature 160℃ reaction time 3 h, mass fraction of abietic acid could be under 1%, mass fraction of dehydroabietic acid was 5.6%, which conforms to the national standards. The regeneration of catalyst was investigated. After cycling five times, the product of hydrogenated rosin still conforms to the national standards without any treatment of catalyst.

在松香5g、m：m：m1：2：2、氯化钯0.090%、n：nl：10、氢气压力5MPa，反应温度160℃，反应时间3h的较佳工艺条件下，产物氢化松香中极酸的质量分数小于1%，去氢枞酸的质量分数5.6%，符合GB/T 14020-2006国家标准；并对催化剂的重复使用性能进行了考察，催化剂相不经过处理直接重复使用5次后，产品氢化松香仍然符合国家标准中关于枞酸和去氢枞酸的指标要求。

The costs of abietic acid separating with A amine salt method and B amine salt method were 1/5 and 1/3 of cost separating with di-n-amylamine salt reported in the literature respectively.

同时研究了以酸异构化、高温异构化和微波辅助酸异构化松香制备枞酸含量较高的异构化松香的实验条件，以异构化松香为原料，采用多种方法分离提纯枞酸，得到最佳分离提纯条件。

First,the content of surfactant should be more than 18 percent and the content of anion surfactant should be kept in proper proportion to the content of nonionic surfactant. Second,the content of zinc naphthenate should be kept in directly proportional to the content of other surfactant. Third,the content of rosin shouldnt too higher and the content of oleic acid should be kept in directly proportional to the content of rosin. Fourth,the content of water should be kept in a low level (less than 8%);otherwise emulsifier oil will delaminate. In addition,the requisite content of sodium heavy alkyl benzene sulfonate is higher than petroleum sulfonate.

试验表明在以松香、重烷磺酸钠、石油磺酸钠为主要乳化剂时，要获得优良的乳化液，需满足以下几个条件：(1)需在乳化油配方中加入适量的乳化剂，且其中阴离子乳化剂总量与非离子乳化剂总量的应保持适当的比例；(2)乳化油中环烷酸锌的量与其它乳化剂总量要保持正比关系；(3)乳化油中松香的量不易过大，且油酸的加入量应与松香量成正比；(4)乳化油中水分含量不易过高(一般不能大于8％)，过高时稳定性不好，易分层。

I will endeavour to find you some assistance.
