The old method of manufacturing stearine is rather cumbersome. Pressing has to be repeated thrice, in order to get rid of the unsaturated acids, otherwise the quality will be inferior This new method is to use soy bean oil or cotton seed oil and Chinese vegetable tallow singly or together as raw materials. After hydrogenation, spliting and distillation, stearine of good quality is obtained. The raw materials must be refined first so that the water content is under 0.1%, the acid number is under 0.5.

The old method of manufacturing stearine is rather cumbersome. Pressing has to be repeated thrice, in order to get rid of the unsaturated acids, otherwise the quality will be inferior This new method is to use soy bean oil or cotton seed oil and Chinese vegetable tallow singly or together as raw materials. After hydrogenation, spliting and distillation, stearine of good quality is obtained. The raw materials must be refined first so that the water content is under 0.1%, the acid number is under 0.5. They are then hydrogenated in a hydrogenator with good stirring, with 0.2-0.25% Ni as catalyst under 5-10 kg/cm2 pressure at 180-200℃. In about three hours, they are almost completely hydrogenated. Spliting conversion reaches about 97% after 6 hrs. The iodine number of the products after distillation is under 1. The product consists of stearic acid and palmitic acid in the ratio of 45:55 or 50:50. It therefore conforms to the specifications as required by the cosmetics industry. This method does not have to use the comparatively Jcarce animal tallows as raw materials.

硬脂酸旧的生产方法,手续繁琐,须经过多次压榨,否则成品中不饱和脂肪酸含量较多,质量就次。本研究系采用豆油或棉子油与桕油分别或混合进行极度氢化后水解,蒸馏即获得质量高的硬脂酸。以含水0.1%以下酸价0.5以下的精炼棉子油与桕油,用0.2—0.25%的镍催化剂,在表压5—10公斤,温度180—200℃情况下,在有良好搅拌的氢化罐内进行氢化,3小时以内即可达到极度氢化。继续裂解,6小时分解率可达到97%左右。成品的碘值在1以下。其中所含十八烷酸与十六烷酸的比例为45∶55或50∶50。因此完全适合化粧品工业所要求的规格。同时也避免了使用国内比较缺乏的牛羊油作为原料。

This Paper describes a diffusion method to seperate fluorinc of plant ma-terial directly from other interferring ions for its determination.After wash-ing with tap water, plant samples were dried at 85℃ for 24-48 hrs.,milledand passed through a 100 mesh sieve.Put the dried powder into a small sty-rene plastic round vessel,o.d. 6cm and 2cm high,with tight cover.Put thesample in the central part at thc bottom, and keep it free from the side wallof the vessel, otherwise, the diffusion process may be affected, Wetting with2ml distilled water, mixing with 2 ml 70% perchloric acid,and put on the co-ver, which has a thin layer of NaOH formed by spreading 0.2 ml IN NaOHin ethyl alcohol on the inner surface.Put the vessel under 50℃±1℃ anddiffusion for 18-20 hrs. At end of the diffusion the diffusate was dissolvedwith H_2O from the cover,the fluorine content was determined by alizarincomplexone spectrophotometrically. The recovery of fluorine from standard NaF solution,either witn or withoutplant samples,is higher than 95%.Experimental error of this method comparedwith that of ashed at 550℃ after adding Mg(NO_3)2, is less than 5%,thatproves this method is satisfactory. Using this method we have determined the F content of leaf, bark andfruit samples from forest and fruit trees,vegetables and farm crops.we aresatified witn our data.

本文报导了用扩散法直接从植物样品中分高氟,以除去干扰离子。样品用水冲洗后,在85℃干燥24—48小时,磨碎后过100目筛。样品放在聚苯乙烯塑盒(外径为6厘米、高2厘米)的底部,先用2毫升蒸馏水湿润,然后加入2毫升70%高氯酸,摇匀并盖好,盖的内面涂有1N NaOH乙醇溶液0.2毫升,干燥后使用。扩散条件:温度50℃±1℃,时间为18—20小时。扩散后,用菌素酪合酮分光光度法测定含氟量。 结果表明,标准氟化钠在有无植物样品时回收率均高于95%;直接扩散与加Mg(NO_3)_2在550℃灰化后扩散相比较,两者误差一般不超过±5%。我们用此方法测定了多种树木、果树、蔬菜和农作物的叶片、树皮和果实较为满意。

Sesbania gum is made from the seeds of Sesbania,an annual legume common- ly grown in China.It is a non-ionic galactose-mannan gum. This paper describes the chemical structure,molecular weight and properties of Sesbania gum and points out that Sesbania gum is a vegetable gum with excel- lent properties.Sesbania gum and Guar gum have the same chemical structure and possess similar properties. Due to its abundance and low cost,Sesbania gum's prospect for widespread use is bright.This paper describes the characteristics of the Sesbania gum gelatine system,techniques and factors involved in the manufacture of slurry explosives using Sesbania gum as gelatizer. Sesbania gum has wide applicability in different types of slurry explosives and processing techniques.Slurry explosives with Sesbania gum as gelatinizer exhibit excellent properties and have played an important role in blasting opera- tion in metal ore mines.

田菁胶是由我国盛产的一年生豆科植物田菁的种籽加工分离得来的,是一种非离子型的半乳甘露聚糖胶。本文叙述了田菁胶的化学结构、分子量和性能特点。指出田菁胶是一种性能良好的植物胶,其化学结构与古尔胶相同,性能特点也与古尔胶极为相似。由于资源丰富、价格较低,使田菁胶具有广泛应用的美好前景。本文还阐述了田菁胶凝胶体系的特性及其在浆状炸药中的应用技术和影响因素,指出了田菁胶是浆状炸药的良好胶凝剂,对不同品种的浆状炸药和加工工艺具有广泛的适应性。以田菁胶为胶凝剂的浆状炸药性能优良,在冶金矿山的爆破作业中发挥了比较重要的作用。
