This is a preliminary report of the application of several methods in the making of bamboo pulp. The two-stage soda process and the two-stage sulfate process were first tested. It was found that the pulp obtained by the second process can be better bleached than that by the first process. In order to im-prove the quality of the pulp, the three-stage sulfate process was then applied. It consists of three steps, namely, cooking in water under slight pressure (115℃) for about one hour, digesting in a solution...

This is a preliminary report of the application of several methods in the making of bamboo pulp. The two-stage soda process and the two-stage sulfate process were first tested. It was found that the pulp obtained by the second process can be better bleached than that by the first process. In order to im-prove the quality of the pulp, the three-stage sulfate process was then applied. It consists of three steps, namely, cooking in water under slight pressure (115℃) for about one hour, digesting in a solution of one percent of the cook-ing reagent (HaOH:Na2S=2:l) at 120℃ for two hours, and finally digesting in a 5% solution of the reagent for three hours. This 3-stage method gave a product which is satisfactorily white and was found equally applicable to sev-eral kinds of bamboo used.

本文系将数量制粕法应用於竹材纸粕之初步研究报告,试以二级碱法及二级硫酸盐法蒸解老竹,发现后者竟较前者更宜於竹材,所得硫酸盐竹粕,经漂白后色泽较碱粕为佳,再试以三级硫酸盐法,先以水於微压下(115℃)蒸煮一小时,次於120℃时以1%蒸解剂(NaOH:Na_2S=2:1)稀溶液预行蒸解两小时,最后以5%蒸解剂溶液蒸解三小时,结果可得洁白之纸粕,对於所用数量竹料均极相宜.第三级蒸解之最宜情况,经试验结果,以在160℃时用5%蒸解剂溶液(NaOH:Na_2S=2:1)蒸解3(1/2)小时之成绩为最佳,所得纸粕色泽既白,且漂剂消耗量亦低.作者曾将竹材皮层与心材剥离,分别以三级硫酸盐法蒸解,证明两者所得纸粕,就色泽及漂剂消耗量而言,大致相同,指示前人理论,谓老竹皮层中含有高分子胶质,纸粕不易漂白,似属不确.本试验仅用三种不同地区所产之竹为原料,故三级硫酸盐法是否适用於所有国产竹材,及其最宜蒸解情观是否完全相同,犹待於将来之研究.

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...

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。

The direct amperometric titration of amines with sodium tetraphenylborate solution based upon anodic depolarization at a dropping mercury electrode by the use of excess TPB titrant, was systematically investigated. The influence of various factors such as pH, volume of titration mixture, quantity of sample in a definite volume to be titrated were studied. Based upon the above observations, a method is proposed as follows: Pipette 0.5-2.0 ml (at a concentration of about 2×10~(-2)M) of samples of various amines...

The direct amperometric titration of amines with sodium tetraphenylborate solution based upon anodic depolarization at a dropping mercury electrode by the use of excess TPB titrant, was systematically investigated. The influence of various factors such as pH, volume of titration mixture, quantity of sample in a definite volume to be titrated were studied. Based upon the above observations, a method is proposed as follows: Pipette 0.5-2.0 ml (at a concentration of about 2×10~(-2)M) of samples of various amines into a 50 ml beaker and add 1% HAc to make a volume of about 10-20 ml. The dropping mercury electrode serves as the polarographic anode. Titrate the amines with 0.05 M standard Na-TPB solution (pH 8) at 0.18 V using the saturated NaCl bridge and S.C.E. as reference. After each addition, stir for one minute and allow the solution to obtain a steady current value, then record the galvanometric reading. The end point is graphically plotted with current versus milliliters of titrant; sharp breaks are obtained. The Na-TPB solution was standardized volumetrically by the standard mer- curic solution. Organic bases so determined include aniline, methyl aniline, diethylamine, ephedrine hydrochloride, dimethylaniline, trimethylamine hydrochloride, triethylamine hydrochloride, urotropine, and tetraethylammonium iodide. The relative error of this method is 2%. The more soluble salts of aliphatic primary amines such as methylamine, ethyl- amine, n-butylamine, and even in the case of ephedrine hydrochloride could not be ac- curately titrated. The application of this method to titrate the amines depend largely upon the structure of the amines and the solubility of amine-TPB salts. This method was also successfully applied to titrate the nitrogen containing drugs such as chlopromarzine, cinchophene, quinine sulphate, atropine sulphate, antipyrine, aminopyrine, rivanol, and strychnine.

本文研究了用pH8的四苯硼酸钠水溶液对胺类的直接电流滴定法.滴汞为阳极,饱和甘汞为阴极,以3%琼脂的饱和NaCl溶液为盐桥组成电解池.适宜的滴定条件是:外加电压+0.18伏;底液为pH 2-3的HAc-NaAc介质,而以1%HAc更为方便;滴定体积为10-20毫升.可测的浓度范围和胺类的四苯硼酸盐沉淀的溶解度有关:仲胺为1×10~(-3)-2×10~(-2M);叔胺为6×10~(-4)-2×10~(-2)M;季胺为4×10~(-4)×10~(-3)M;伯胺类不能测定.方法的相对误差因沉淀的溶解度而异,一般在2%以下.滴定时沉淀可不必分离,且无需除氧,操作步骤比较简易.
