The plant expression vectors were constructed and two genes were transferred into A. thaliana and N. tabacum, antikanamycin plants were obtained.4. The trials of adventive bud regeneration directly and callus induction was conducted to select out the optimal explants and formula. The results revealed that double scale can produce 13~16 adventive buds per centimeter in MS medium added 10.0 mg/L 6-BA, 1.0 mg/ L NAA, 40 g/L sugar and 7.5 g/L agar. Scale, leaves, scape and different tissue of flower can be induced to produce callus in appropriate medium, but the filament with anther was the optimized explant.

PVA-2080 is one of the important dispersing agents to produce loose polyvinyl chlorid. At present KH-20 is mainly imported from Japan to take the place of the traditional gelatin to produce high quality PVC in our country. In order to solve this problem, we exploit PVA-2080 to replace the foreign products. The experiment includes two steps of polymerization and a process of partial alcohlysis. After a number of trials, we get a product of white particles.Its average degree of alcoholysis is 80.77% and t...

聚乙烯醇- 2 0 80 (PVA - 2 0 80 )是生产疏松型聚氯乙烯的重要分散剂之一目前，国内主要依靠进口日本的KH - 2 0以代替传统的明胶来生产高质量的PVC产品为了解决这一问题，作者开发了PVA - 2 0 80 ，以代替国外进口本试验经过两步聚合和部分醇解等过程，通过正交试验优化试验条件，得到了外观为白色粉末状颗粒、平均聚合度为 2 0 4 2、醇解度为 80 。77%的产品经小釜应用试验，效果比较理想

During the reaction of alkylation, general contained 0.2%~2.0% butadiene will produce viscous heavy composite materials, which will raise final boiling point of alkylate and decrease octane, what is more, it will react with acid to produce corresponding ester, which will increase the consumption of acid, Therefore, we must remove butadiene by selective hydrogenation, at the same time, it will convert some of 1- butane to 2- butane by isomerization and raise octane of alkylate.

一般含有0.2%~2.0%的丁二烯，其在烷基化反应中，可生成一种分子量很高的粘稠重质迭合物，使烷基化油的干点升高，辛烷值降低，并且它还和酸反应生成相应的酯而加大酸耗量。因此必须经过选择性加氢除掉丁二烯，同时，将部分1-丁烯异构化为2-丁烯，以提高烷基化油的辛烷值。
