以水合肼、双氧水和硼酸为催化体系,对天然以水合肼、双氧水和硼酸为催化体系,对天然胶乳进行非贵金属催化的原位母体加氢,并用核磁共振氢谱对氢化天然胶乳的结构进行表征。结果表明,氢化度随着硼酸用量的增加而增大,当硼酸/碳碳双键(摩尔比)达到0.25时,天然胶乳的加氢度接近60%
Hydrazine hydrate, hydrogen peroxide and boric acid as catalyst system, the natural hydrazine hydrate, hydrogen peroxide and boric acid as a catalyst system, non-noble metal catalyst in situ latex parental hydrogenation, and hydrogen nuclear magnetic resonance hydrogenated latex structure Characterization. The results show that the degree of hydrogenation increases with the increase of the amount of boric acid. When the ratio of boric acid / carbon-carbon double bond (molar ratio) reaches 0.25, the degree of hydrogenation of natural rubber latex is close to 60%
