| 摘 要： | 通过核磁共振技术(1H,13C NMR,DEPT135,COSY,HSQC,HMBC)和红外光谱技术(FT-IR),对未知的有机硅表面活性剂商品(NPS-A)进行了表征;结果表明:该表面活性剂是单烯丙基聚乙二醇(AllyloxyPolyEthylene Glycol,APEG)在聚硅氧烷侧链改性所得,样品中含有合成时所带的大量DMSO溶剂(合成时所代入的),除溶剂外的主要成分为:(1)M-D20-(D′R)6-M(M:三甲基硅氧基;D:二甲基硅氧基;D′:取代的二甲基硅氧基),其中R=CH2CH2CH2-O-(EO)8-H,平均分子量(M_n)为4 046.0,(2)APEG(M_n=410.0)和(3)聚乙二醇(PolyEthylene Glycol,PEG,M_n=370.0),同时还含有少量由烯丙基衍生而来的小分子成分.

| Abstract: | Unknown silicon surfactant (NPS-A) was characterized by FT-IR and NMR spectra (including 1H NMR, 13C NMR, DEPT135, COSY, HSQC and HMBC). The results indicated that the sample is a polyether modified silicon surfactant. It is a mixture of three ingredients dissolved in DMSO: (1) M-D20-(D′R)6-M [M:trimethylsiloxane group; D: dimethylsiloxane group; D′: substituted dimethylsiloxane group and R=CH2CH2CH2-O- (EO)8-H] with a mean molar weight of 4 046.0, (2) AllyloxyPolyEthyleneGlycol (APEG) with a mean molar weight of 410.0 and (3) polyethylene glycol (PEG) with a mean molar weight 370.0. Furthermore, trace amount of compounds derived from allyl group were identified. |
