摘要
选择四甲基四氢环四硅氧烷作模型化合物，利用Ｓｉ－Ｈ伸缩振动在２１６Ｏｃｍ￣（－１），的吸收作定量分析峰，以红外光谱法测定含氢硅油和烯丙基醚加成产物中残留Ｓｉ－Ｈ的含量，所得结果与化学法测定结果一致。
In this paper a new way for the determination of Si-H groups content in the addition product of hy-drogen polysiloxane fluid and allyl-ether by means of IR was described,selecting tere-methyl tere-hydrogencyclosilicone as model compound and Si-H stretching vibration(2 1 60cm￣(-1))as qualitative analysis absorp-tion bands.The results showed there was no difference with that of chemical analysis.
