An addition product which is very likely a β-sultone was obtained from the spontaneous reaction between chlorotrifluoroethylene and sulfur trioxide as a distillable colorless liquid (Ia+Ib; b. p. 76.0—76.5°, n_D~(20°) 1.3672, d~(21.8°) 1.71). Its structure was elucidated by elementary analysis, determinations of molecular weight and saponification equivalent, and its infrared spectrum.

An addition product which is very likely a β-sultone was obtained from the spontaneous reaction between chlorotrifluoroethylene and sulfur trioxide as a distillable colorless liquid (Ia+Ib; b. p. 76.0—76.5°, n_D~(20°) 1.3672, d~(21.8°) 1.71). Its structure was elucidated by elementary analysis, determinations of molecular weight and saponification equivalent, and its infrared spectrum. Preliminary studies of its chemical behavior are also here reported.Similarly, from the reaction of sulfur trioxide with 4, 5-dichloroperfluoropentene1 (IV), 4, 6, 7-trichloroperfluoroheptene-1 (V)、4, 6, 8, 9-tetrachloroperfluorononene-1 (VI) and 4, 6, 8, 10, 11-pentachloroperfluoroundecene-1(VII) compounds were also obtained namely; (VIII) (b. p. 79.8—80.0°/63.7mm, n_D~(22.2°) 1.3642)、(IX) (b. p. 56°/0.17 mm, n_D~(20.5°) 1.3800)、(X) (b. p. 81—82°/0.08 mm, n_D~(20°) 1.3893)、 and (XI) (b. p. 115—116°/0.40 mm, n_D~(20°) 1.3949). The yields ranged between 70% and 80%.The addition of sulfur trioxide to 4, 4-dichloropernuorobutene-1 and 2,3-dichloroperfiuorobutene-2 yielded products of lesser purity. From the same reactions, the formation of products which possibly were the carbyl sulfates of these two butenes were noted. The products obtained from the reaction of sulfur trioxide with 1, 2-dichloroperfluoroethene and perfluoropropene were mixtures.

本文报告三氧化硫和氯三氟乙烯的加合反应,以及由此而得的一衍生物。各种定量分析、化学反应和光谱结果指示最合理结构是一个四员杂环的β-磺内酯(Ia+Ib)。对于这一个衍化物的化学性能,也作了初步的研究。同样的,从液体三氧化硫与4,5-二氯全氟戊烯-1、4,6,7-三氯全氟庚烯-1、4,6,8,9-四氯全氟壬烯-1、4,6,8,10,11-五氯全氟十一烯-1的加合反应产物内,经分馏后也可以得到颇为纯粹的同类衍化物(β-磺内酯),产率为70—80%。4,4-二氯全氟丁烯-1以及2,3-二氯全氟丁烯-2与三氧化硫反应后所得的产物则不甚纯净;1,2-二氯二氟乙烯以及全氟丙烯与三氧化硫的反应产物则更不纯净。

Based on the comparison of the infrared spectra of polyamide homologues, on the changes in the infrared spectra of deuterated and iodine-treated samples of polycaprolactam, and also on the observations of the infrared dichroism of drawn film, the main absorption bands of polycaprolactam in the region 400 cm(-1)-1400cm-1, which are rather structure sensitive, have been assigned as follows: 1370 cm-1 band-VC-N;, 1265 cm-1 and 1205 cm-1 bands-(Amide Ⅲ); 1170 cm-1 band-VC-N; 730 cm-1 band-γCH2...

Based on the comparison of the infrared spectra of polyamide homologues, on the changes in the infrared spectra of deuterated and iodine-treated samples of polycaprolactam, and also on the observations of the infrared dichroism of drawn film, the main absorption bands of polycaprolactam in the region 400 cm(-1)-1400cm-1, which are rather structure sensitive, have been assigned as follows: 1370 cm-1 band-VC-N;, 1265 cm-1 and 1205 cm-1 bands-(Amide Ⅲ); 1170 cm-1 band-VC-N; 730 cm-1 band-γCH2 of (CH2)n when n≥4; 690 cm-1 band-σN-H (out of plane, Amide V); 580 cm-1 band -σN-H (out of plane).

根据对聚酰胺类高聚物红外光谱的类比和对聚酰胺6试样进行氘化和碘处理后红外光谱的改变,以及根据对拉伸过的聚酰胺6薄膜试样的偏振红外光谱的观察,我们对聚酰胺6红外光谱中400cm~(-1)—1400cm~(-1)之间的主要吸收带,作了如下解释:1370cm~(-1)吸收带为ν_(c_щN);1265cm~(-1)和1205cm~(-1)吸收带为δ_(N-H)+ν_(c_щN)(酰胺Ⅲ);1170cm~(-1)吸收带为ν_(c_N);730cm~(-1)吸收带为γ_(CH_2)[当(CH_2)_n的n≥4时];690cm~(-1)吸收带为δ_(N-H)(面外);580cm~(-1)吸收带亦为δ_(N-H)(面外)。

3-Methylmercapto-5-hydroxy-6-methyl-1, 2, 4-triazine (Ⅱ) reacted with p-toluenesulfonyl chloride in anhydrous pyridine to give N-[5-(3-methylmercapto-6-methyl)-1, 2, 4-triazinyl]pyridinium chloride (Ⅷ), the latter compound gave O-[5'-(3'-methylmercapto-6'-methyl)-1', 2', 4'-triazinyl]-3-methylmercapto-5-hydroxy-6-methyl-1, 2, 4-triazine (Va) on refluxing with water containing small amount of pyridine.

3-Methylmercapto-5-hydroxy-6-methyl-1, 2, 4-triazine (Ⅱ) reacted with p-toluenesulfonyl chloride in anhydrous pyridine to give N-[5-(3-methylmercapto-6-methyl)-1, 2, 4-triazinyl]pyridinium chloride (Ⅷ), the latter compound gave O-[5'-(3'-methylmercapto-6'-methyl)-1', 2', 4'-triazinyl]-3-methylmercapto-5-hydroxy-6-methyl-1, 2, 4-triazine (Va) on refluxing with water containing small amount of pyridine. The structure of O-[5'-(3'-methylmercapto-6'-methyl)-1', 2', 4'-triazinyl]-3-methylmercapto-5-hydroxy-6-methyl-1, 2, 4-triazine (Va) was elucidated by its hydrolysis to 3, 5-dihydroxy-6-methyl-1, 2, 4-triazine (Ⅵ) with aqueous chloroacetic acid or hydrochloric acid and to 3-methylmercapto-5-hydroxy-6-methyl-1, 2, 4-triazine (Ⅱ) with aqueous sodium hydroxide. Ammonolysis of O-[5'-(3'-methylmercapto-6'-methyl)-1', 2', 4'-triazinyl]-3-methylmercapto-5-hydroxy-6-methy-1, 2, 4-triazine (Va) with diethylamine gave 3-methylmercapto-5-diethylarnino-6-methyl-1, 2, 4-triazine (Ⅶ) which formed high melting-point substances on hydrolysis with aqueous solution of hydrochloric acid or sodium carbonate. The infrared spectra of some 1, 2, 4-triazine derivatives were studied.

3-甲硫基-5-羥基-6-甲基-1,2,4-三嗪(Ⅱ)在无水吡啶中与对甲苯磺酰氯作用,得氯化N-[5-(3-甲硫基-6-甲基)-1,2,4-三嗪基]-吡啶鎓盐(Ⅷ)。它在含微量呲啶的水溶液中回餾得結构可能是O-[5′-(3′-甲硫基-6′-甲基)-1′,2′,4′-三嗪基]-3-甲硫基-5-羥基-6-甲基-1,2,4-三嗪(Va)的化合物。此化合物与二乙胺作用得3-甲硫基-5-二乙氨基-6-甲基-1,2,4-三嗪(Ⅶ),后者水解得高熔点的物貭。O-[5′-(3′-甲硫基-6′-甲基)-1′,2′,4′-三嗪基]-3-甲硫基-5-羥基-6-甲基-1,2,4-三嗪(Va)的結构是借其水解反应及胺解反应等加以推論。对于这类化合物的紅外吸收光譜也进行討論。作者对于3-甲硫基-5-羥基-6-甲基-1,2,4-三嗪在吡啶中与对甲苯磺酰氯作用生成O-[5′-(3′-甲硫基-6′-甲基)-1′,2′,4′-三嗪基]-3-甲硫基-5-羥基-6-甲基-1,2,4-三嗪(Va)的反应历程提出建議。
