In this paper a modified method is recommended for the determination of rubber hydrocarbon present in kok-saghyz rubber by means of bromination.This method is rapid and accurate.A conversion factor of 0.298 is obtained for con- verting rubber bromide content to rubber hydrocarbon content for kok-saghyz rubber.The conversion factor agrees well with the theoretical value.

本文报告了用重量溴化法测定青橡胶草生胶中橡胶烃的各种适宜条件,并求得了由溴化橡胶换算为橡胶烃的换算因数为0.298。三氯甲烷可用来防止溴化橡胶的结膜,同时并可防止溴与橡胶的置换反应。每10毫升橡胶液应加溴化溶液2毫升。溴化反应可在常温进行。三氯醋酸可使橡胶容易溶解,对分析结果无显著影响,用或不用均可。溴化法无论在分析时间上和精确度上,均较直接抽提法和间接测定法为优。

The stoichiometry of the synthesis from CO and H_2 is studied. By performing carbon, hydrogen and oxygen balances around an overall chemical equation, a number of stoichiometric equations relating the various reaction criteria have been obtained. Two of them are given as follows: c=1/3(2-u+m+e_1+d), and K=COx(3-4c+δ). where c, m, e_1=moles of CO_2, CH_4 and C_2H_6 formed per mole of CO converted, respectively; K=volume contraction, per cent; x=CO conversion, per cent; u=H_2/CO usage ratio; CO=volume fraction...

The stoichiometry of the synthesis from CO and H_2 is studied. By performing carbon, hydrogen and oxygen balances around an overall chemical equation, a number of stoichiometric equations relating the various reaction criteria have been obtained. Two of them are given as follows: c=1/3(2-u+m+e_1+d), and K=COx(3-4c+δ). where c, m, e_1=moles of CO_2, CH_4 and C_2H_6 formed per mole of CO converted, respectively; K=volume contraction, per cent; x=CO conversion, per cent; u=H_2/CO usage ratio; CO=volume fraction of CO in synthesis gas; and d, δ=correction terms which can usually be neglected. Various applications of the deduced stoichiometric relationships are described, including methods of testing the consistency of synthesis data, a thorough discussion of the significance of reaction criteria and examples to illustrate the use of the derived equations in certain process computations and in correlation of experimental data. For the calculation of contractions, additional formulas are derived to supplement the work of Bashkirov and of Rapoport.

本文从CO+H_2合成的一个总反应式出发,进行碳、氢和氧三个元素的平衡,结合考虑了反应前後气相分子数的改变,得到一些能够说明反应的基本数量指标间关系的公式,其中较重要的有: c=1/3(2-u+m+e1+d) 及 K=CO_x(3-4c+δ). 式中c、m、e1各为以转化的CO为基数时,CO_2、CH_4、C_2H_6的生成率;K、x、μ各属反应的收缩率、CO转化率和H_2/CO消耗比;CO为原料气中一氧化碳的体积分数;d与δ属可忽略的校正项。合成实验结果表明,对同一催化剂在一定反应压力和循回比下,c几不随x而改变。因此,在原料气不变时,K与x约成正比。根擦推导出的关系式,对各反应指标的意羲及其间关系作了较确切的解释;并提供了一些检验数据准确度和快速判断反应情况的方法。从上述公式推导出来的收缩率计算式補充了,和等人的工作。最後,举例说明了元素平衡的关系式可以方便地用到某些合成工艺计算以及实验数据的初步联系上去。

B-Phenylethyl alcohol has been synthesized from styrene through its conversion into styrene bromohydrin, which was dehydrobrominated to its epoxide and followed by hydrogenation. An aqueous solution of 105g. NaClO3 in 225ml. H2O and a mixed solution of 360 g. NaBr in 750 ml. H2O and dilute H2SO4 were added simultaneously into 210g. of styrene during 3.5-4 hrs. at 90-95℃ with vigorous stirring. After completing the reaction, the organic layer was separated and washed with water and dilute soda solution successively. The separated oil, distilled under vaccum, gave an yield of 80-85% styrene bromohydrin, b. p. 106-111℃/2-3 mm., nD23.5 1.5770. Treating it with slight excess of a dilute solution of NaOH at 60-65℃, for 3-4 hrs. gave styrene oxide, b. p. 60-65℃/3-4 mm. nD22 1.5350, d1G1G 1.055, 80-85% in yields, 100 g. of styrene oxide, dissolved in 200 ml. ethyl alcohol, containing 3.3 g. NaOH was hydrogenated in the presence of Raney Ni catalyst under 3 atmosphere at room temperature to give β-phenylethyl alcohol, nD20 1.530, d20 1.0206, 75% in yields.
