查询词典 dithiobenzoic

The thermal decomposition yielded unsaturated compound and dithiobenzoic acid, leading to some loss of living character of the polymerization, such as retarded reaction rate and broadened molecular weight distribution.

我们根据合成双硫酯的经验和实验中的观察发现，双硫酯的热稳定性对RAFT聚合影响很大，在较高的温度下双硫酯会发生一定程度的热分解，生成的双硫酸会对聚合有一定的阻聚和延迟作用。

In our previous work,we found that CDB underwent remarkable thermal decomposition at 90～120℃,which yields dithiobenzoic acid and related derivatives,it can affect the polymerization rate, molecular weight,and molecular weight distribution of the resulting polymers.

我们组发现一种常用的链转移剂CDB在加热情况下会发生热分解，分解产生的双硫酸会对RAFT过程产生一定的阻聚影响，同时使聚合部分不可控，即产物分子量不可控和分布变宽。

The sodium dithiobenzoic acid was oxidized with potassium ferricyanide to obtain di disulfide.The influences of raw materials mole ratio,stirring method and reaction time on the yield were studied with orthogonal test.
