从废次烟草浸膏中提取茄尼醇的皂化试验
The pyridine/water solvent was replaced by n-porpyl alcohol/ethylene glycol solvent in determination of saponification number during esterified process.
将测定酯化产物皂化值的吡啶/水溶剂改为正丙醇/乙二醇溶剂,克服了吡啶/水溶剂的刺激、腐蚀性,同时也改善了溶剂自身方面对测试结果带来的不利影响,提高了分析的稳定性及准确性。
It investigates determination of mixed contents for saponification reaction in physical chemistry experiment based on reaction principle of concentration salt system.
应用浓盐体系反应原理研究了在物理化学实验课中皂化反应混合物含量测定问题 ,表明在饱和NaCl的作用下 ,当NaOH与NaAc的摩尔之比在 1～ 2时 ,获得最佳的实验效果 ,同时在实验教学中也取得了很好的效
In order to reduce the vapor consume and enhance the content of the propylene epoxide at the top of the saponification column, we use the software of ECSS to analyse the energy using of propylene epoxide saponification tower.
以降低环氧丙烷生产中的蒸汽消耗和提高皂化塔塔顶出料中环氧丙烷含量为目的,利用ECSS软件对氯丙醇皂化塔的用能情况进行了分析,通过模拟不同回流比、进料位置、操作压力下塔的耗能的情况,得出皂化塔的最优操作条件,在塔顶出料中环氧丙烷摩尔含量基本不变的情况下,新鲜蒸汽的消耗量降低了63。
