The quality of water used in the purification of linter pulp exerts a decisive influence on the iron content of the product. Laboratory results show theft the absorption of trivalent iron by de-ashed cellulose possesses the character of surface absorption and obeys Freundlich's equation. At the some concentration, the amount of bivalent iron absorbed is far less than trivalent iron; the mechanism of absorption is also quite different. Based on these informations, proposals aro made for reasonably controlling...

水質对于精煉棉漿含铁量的高低具有决定性的影响。实驗室結果显示,高铁纖維素所吸收系表面吸附性質,且遵从Freundlich吸附规律。在同一濃度时,低鉄的吸收量远较高鉄为小,机理也不同。这些資料对合理控制精煉棉漿的含鉄量頗有帮助。

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。

The basic oxygen steel-making process is another important technical revolution following the Bessemer process and the Thomas process. It is now playing a vital part in the steel industry in countries like West European countries, Japan, etc. After taking stock of the present steel production and modern development in several leading countries and after comparing various kinds of oxygen steel-making processes, the author points out that the basic oxygen steel-making process is the main trend in steel production from now on. In his thesis, the author compares by illustrations the basic oxygen process and the open-hearth process in the following respectsthe methods of operation, the suitability of raw materials, the total yield, production costs, and the investments in basic construction. He also points out with emphasis that the basic oxygen process surpasses the open-hearth process in the kinds of products and their quality. He takes into considerations of the resources and the conditions of production of our country, and gives his personal opinion at the end of his thesis: The question of making immediate use of oxygen is on the programme today. The rapid development of oxygen steel-making should become one of the significant measures to push forward the production of the whole industry.

碱性氧气轉炉炼鋼法是继貝士麦炼鋼法和托馬斯炼鋼法之后又一次重要的技术革命,已經在若干国家如西欧国家、日本等炼鋼工业中起着巨大的作用。作者从世界上几个主要产鋼国家现时生产和发展的形势,在比較了不同类型的氧气炼鋼方法后指出:碱性氧气轉炉冶炼是今后炼鋼的一个主要发展方向。文中作者用实例就碱性氧气轉炉的操作方法、原料的适应性、金属收得率、产品成本以及基建投资等方面与平炉作了对比,并着重指出:碱性氧气轉炉鋼在品种和质量方面与平炉鋼相比較,实有过之而无不及。作者結合我国资源和生产情况,在文末提出个人意見,认为:氧气在我国冶金工业中的加速使用已經提到日程上来。加速发展氧气炼鋼应成为进一步推动整个工业生产的重大措施之一。
