bromating

Preparation and XPS study of gradient bromating amorphous hydrogenated carbon film

掺溴非晶碳梯度薄膜的制备与分析

Residue double bonds in PDA were determined by bromating method, and the effect of reaction temperature, time and pH value were explored.

通过溴化法对PDA中总残余双键进行测定，对分析过程中反应温度、时间和pH值进行了研究。

In order to make the gradient bromating amorphous hydrogenated carbon film, this article first manufactured the automation to control the Mass-Flow-Control which is produced by MKS Corporation, and has compiled this equipment automation control procedure using the VB senior programming language.

本文为制备掺溴非晶碳氢薄膜材料，首先制作了自动化控制MKS公司出产的质量流量控制计装置的接口电路，并利用VB高级编程语言编写了该装置的自动化控制程序。

By bromating method of determine the different value of total double bond in PDA, the content of residue DM could be obtained, the detection limited 0. 5%.

采用容量法测试共聚物中总双键量通过差值得到共聚物PDA中残余单体DM的含量，测试下限为0.5%。

The first route was carried out by bromating, dehydrating, replacing reaction.

路线二经过溴化、脱水、酯化、取代、水解反应得到中间体；
