Based on the laboratory results of the Institute of Petroleum, Academia Sinica, on urea extractive crystallization, a pilot plant with a capacity of 0.15 ton per day has been constructed & operated. With water as urea solvent and an organic chlorine compound as activator, the adducts formed into small spheres which are easily filterable. The main characteristics of the process developed was that the adduction, filtration, washing and decomposition operations were carried out in the same vessel. The design data for a commercial plant were obtained during the pilot plant run. Satisfactory dewaxing results were obtained for both light and heavy petroleum fractions with various wax contents. For light petroleum fractions, the freezing point can be lowered to below-70C. The process developed is suitable for manufacturing speciality low freezing point petroleum products, and the n-paraffins obtained after refining are good raw materials for making higher alcohols, detergents, etc.

在处理量为0.15吨/日的中型设备上,进行了不同原料油的尿素脱蜡试验。用尿素饱和水溶液,有机氯化物为活化剂,生成的尿素-正烷烃络合物成球状,易於过滤分离。在中型试验装置上取得了各单元处理的基本数据。对於含蜡不同的轻、重石油馏份,均能获得满意的脱蜡效果;轻馏份冰点可至-70℃以下。本法适用於制造低凝固点石油产品。所得正烷烃中芳香烃含量甚少;精制除去胶质后,可作为氧化制醇的优良原料。 尿素脱蜡方法,系利用尿素能与正构烷烃选择络合结晶析出的性质,使石油馏份中之正烷烃分离。此法在分析室中已被用来测定油品中正烷烃之含量。关於其在工业中之应用,各国自1947年起即已开始研究,建立了中型试验及工业化生产设备。现苏联已建成世界最大的工业化生产厂,於1957年开工。各国所用方法流程均不相同,其大致情况如表1所示。

The lymph node and spleen from rhesus monkeys sensitized with BCG and tetanus toxoid were homogenized in ice-water bath. After centrifugation the supernant was filtered through a dextran G25 gel column and was separated into 6 fractions. In skin tests fraction Ⅳ was shown to transfer antigen-specific cutaneous delayed hypersensitivity to normal rhesus monkey, high dose of fraction IV might be promising to transfer delayed hypersensitivity to man.

将对结素和破类呈现阳性皮肤延迟超敏反应的恒河猴的淋巴结和脾脏剪碎,匀浆,过滤和高速离心,以葡聚糖G25凝胶过滤分离成6个组分。只有组分Ⅳ不仅能将皮肤延迟超敏反应在同种异体之间转移,而且能从恒河猴转移到人。不管TF供体和培养淋巴细胞供体对抗原的应答如何,所有组分均有增强SK—SD刺激淋巴细胞转化作用,组分Ⅲ和Ⅳ的混合物作用最强。组分Ⅲ和Ⅳ对人的淋巴细胞亦有类似的作用。因此,恒河猴TF增强抗原刺激淋巴细胞转化的作用是没有抗原特异性和种属特异性的。 初步的生化分析表明,组分Ⅳ含有RNA,多肽和次黄嘌呤,薄层色谱有2个254nm紫外光吸收成分和2个节三酮显色成分,等电点聚焦电泳时出现17条考马斯兰R250着色带。 这些结果说明,有可能用恒河猴制备某些人类疾病的特异性TF。

A Complete description of the method for sampling respirable dust from ambient air and analytical proeedure is given with reference to free silica, Fe, Mg, Cu and Pb, in the same sample. Sampling is accomplished by BDX44 Super Sampler and BDX99R Respirable Dust Sampling Head. The silicate minersls and metals are dissolved by heating the sample with phosphoric acid. Free silica residue is separated by filtration. The filtrat is used for determining metals. The residue is dissolved with hydrofluoric acid and then a silicomolyb-date complex is formed in a malybdate solution. The solution is used for determining silicon. All the analyses are done by flameless AAS.The detection limit is 4.5ug, the coefficient of variation is 8.2% for free silica. Results are reported from some different workplaces.
