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 poisoning effects of 11 nitrogen compounds on 5 different kinds of oils (Yumen heavy diesel oil, Fushun acid Washed light shale oil, cetane, decalin, etc.) were investigated, the main purpose being to study the poisoning mechanism of different classes of nitrogen compoands on different cracking feed stocks. The results indicate that the poisoning effect of the pyridine and pyrrole classes of nitrogen compounds on the cracking activity and selectivity of the above mentioned oils is similar to that found in our precious reports. However, there is no such independent and additive property between the poisoning effects of these two classes of nitrogen compounds as found before. The poisoning curves produced by these two classes are also different: the pyridine class causes exponential decrease in activitv while pyrrole causes linear decrease. Furthermore, the poisoning effect of the pyridine class on the cracking selectivity, as expressed by the carbon number distribution of cracked products, is different for shale oil and petroleum. On the basis of these results, a poisoning model involving two different kinds of active centers as well as two different kinds of poisoning mechanism is proposed. By means of this model, the main results found in this and previous reports can all he explained.

研究了十一种氮化合物对玉門脫腊重柴油、酸洗撫順頁岩輕油、十六烷及十氫萘等五种油料的中毒作用,主要目的在于考察不同系氮化合物对不同裂化进料油的中毒作用。 結果发現吡啶系与吡咯系氮化合物对于五种油料的裂化活性与选择性的影响与前两报結果相似,但与前不同的是两系氮化合物的毒性之間却不存在独立而可加的現象。此两系氮化合物的中毒曲綫也有所不同:吡啶系使裂化活性成指数关系下降,然而吡咯系却使其直綫下降,此外还发現吡啶系中毒对天然油与頁岩油的裂化选择性(裂化产品的碳数分布)的影响也不同。根据这些結果,提出了两种活性中心及两种中毒机理的模型。以此模型可以解释本报告及前数报中的所有主要結果。

A strain of hydrocarbon-oxidizing bacterium isolated from local garden soil by enrichment culture method grew profusely in paraffin oil culture medium. All nalkanes of C_(12)-C_(18) as well as paraffin wax (m. p. 58-60℃) are easily oxidized by this microorganism, but their lower homologs and branched alkanes are quite resistant to the oxidation. The respiratory quotient of n-hexadecane and n-octadecane were found to be 0.44 and 0.47 respectively.The microbial oxidation of fatty alcohols (C_8-C_(18)) is similar to that of the corresponding alkanes. The rate of oxygen consumption of C_8-C_(18) fatty acids (10~(-3)M Na-salt) is nearly the same. These results may further support the hypothesis that the alkane oxidation most likely passes through the intermediate steps of the corresponding alcohol and fatty acid and finally enters the β-oxidation system.Some aromatic, naphthenic and other related compounds have also been tested.They showed either neglegible oxygen uptake or even suppressed the endogenous respiration.Azide, cyanide, iodoacetate, heavy metals(Hg~(++),Cu~(++), Co~(++))and α,α'-dipyridyl(5×10~(-5)to 5×10~(-3)M) inhibited the oxidation of n-hexadecane as well as n-hexadecyl alcohol to the extent of more than fifty per cent.The mechanism of the hydrocarbon oxidation by this bacterium and the enzyme systems possibly involved were discussed.

我们从土壤中分离得到一株烃类氧化菌,在石蜡油培养液中振荡培养,繁殖迅速,菌体呈亲油性。该菌能够氧化C_(12)、C_(14)、C_(16)、C_(18)等正烷和石蜡(熔点58—60℃)。正辛烷和正癸烷的氧耗率低于或等于内源。异烷似较难氧化。对正十六烷和正十八烷的呼吸商依次为0.44 和0.47。该菌对脂肪醇的氧化性能与烷类相似。C_(12)—C_(18)脂肪醇氧耗率相当高,低于正癸醇的醇类的氧化则不明显。C_8—C(18)脂肪酸钠盐(10~(-3)M)的氧耗率大抵相等。苯、甲苯(以上为饱和水溶液)、萘、蒽、菲、四氢萘、十氢萘、胆甾醇、胆酸钠(10~(-3)M)和高级脂肪醇硫酸酯的氧化都不明显或有抑制作用。各种浓度的迭氮化钠、氰化钠、碘醋酸、Hg~(++)、Cu~(++)、Co~(++)、a,a′-二联吡啶对菌氧化正十六烷和正十六醇有不同程度的抑制作用。根据以上结果,对菌体内烷烃的氧化途径及酶的性质作了某些推测和讨论。
