    The influence of mineral compositions and their grain size, shapes, surface conditions, etc. of the base sand as well as the purifying processes on the strength of cold-setting resin sand mixtures are investigated. The mechanism of the effects and the evaluation of various purifying processes are discussed. It is proposed that the rubbing and washing process as a puiifying means is well worth popularizing and a careful selection is necessary in ordei to upgrade the base sand for use in steel...

    Dilute acetic, sulfuric and hydrochloric acids are used as solvents in extracting berberini from Berberis kansuensis schneid. The results showed that the dilute acetic acid is the most satisfactory one, while the dilute sulfuric acid is better than the hydrochloric acid. The amount of solvent used in extracting is about 5—6 times the crude material. The amount of the salt in the "saltdialysis" is about 3%—5%(W/v) of the volume of the collected berberini solution. It should not be less than 3%(W/v). After adding...

    Dilute acetic, sulfuric and hydrochloric acids are used as solvents in extracting berberini from Berberis kansuensis schneid. The results showed that the dilute acetic acid is the most satisfactory one, while the dilute sulfuric acid is better than the hydrochloric acid. The amount of solvent used in extracting is about 5—6 times the crude material. The amount of the salt in the "saltdialysis" is about 3%—5%(W/v) of the volume of the collected berberini solution. It should not be less than 3%(W/v). After adding concentrated hydrochloric acid and salt, the collectd berberini solution must be kept still more than 24 hours in order to cause the berberini hydrochloride to precipitate Completely. Such conditions as temperature(80—90℃) and pH Value(8—9) must be controlled throughout the purifying process of the berberini base. The contents of berberini in the whole root section of Berberis chuingu chen from xinglong Mountain near lanzhou has been determined to be 0.57%.

    本文报告以小型生产为目的,对酸水法由三颗针提取小檗硷的有关条件进行了试验,据此拟定的操作方法在生产中证实是可行的,并从生产考虑,测定了兴隆山三颗针中小檗硷的含量,其结果为: 1、根皮含小檗硷为 3.75%~3.71% 2、杆皮含小檗硷为 0.81%~1.01% 3、全根切片含小檗硷约为 0.57%

    A detailed review of traditional zinc strip purifying technology for electrolytic solution of dry cell is presented. The traditional technology is simple. It can remove overall harmful impurity and use waste zinc slices. So it has been employed for a long time. However, there are some defects, e.g. the longer purifying process period, the more consumpion of coal and zinc. Now the traditional purifying technology is replaced by the advanced rapid purification process.

    传统的吊锌法工艺简单、除杂全面、能利用本厂的废锌角,因而长期地被广泛采用。但吊锌法周期长、耗煤耗锌多、除杂能力不强、生产方法落后,目前正处在被先进的快速净化工艺取代的阶段。
