Distribution of chlorine gas as fully dispersed fine bubbles in pulp suspensions is one of vital conditions for the optimization of chlorination in a bleach plant. Direct injection of chlorine gas into pulps or poor performance of gas dispersion would result in obvious defects such as non-uniformity of pulp chlorination, coexistence of over- and under-chlorinated fibers. This would also bring about unnecessary excess chemical consumption.Investigated in this paper are conditions to realize and maintain dispersed...

Distribution of chlorine gas as fully dispersed fine bubbles in pulp suspensions is one of vital conditions for the optimization of chlorination in a bleach plant. Direct injection of chlorine gas into pulps or poor performance of gas dispersion would result in obvious defects such as non-uniformity of pulp chlorination, coexistence of over- and under-chlorinated fibers. This would also bring about unnecessary excess chemical consumption.Investigated in this paper are conditions to realize and maintain dispersed state of C12 gas in water in a lab-scale disperser. Experiments indicate that water /C12 (weight ratio) should not be lower than 57 (20℃, 400 kPa) when cold water is used as the dispersing medium. In the first 1/4 second, gas bubbles of 0.52 mm predominate and tend to increase in size gradually. The tendency of coalescence is. striking with the increase in the system temperature. It is recommended that the time for the gas-water mixture to get from the disperser to the pulp stream should not be any more than 1 second. Should water/gas weight ratio be too low, plug flow will be observed.

氯气以充分分散的细小气泡分布在浆流中,是实现漂白一段氯化最佳化的重要条件。氯气直接通入浆中或分数装置效能不好造成的弊病是明显的:纸浆氯化不均匀,过氯化和氯化不足同时出现和化学品的浪费。 本文探讨了在实验室的氯水分散器中实现并保持氯气充分分散的各种条件。结果表明:以冷水为介质使氯气分散的水/氯气重量比不要少于57(20℃,400kPa),此时气泡初期尺寸为0.52mm,1/4秒后即可扩大。系统温度升高聚合趋势更加明显。氯-水混合物从分散器出来进入浆流的时间不宜超过1秒。若水/氯气重量比降低,则会转为柱塞流。

The classic method for determining gangliosides (Gls) species in tissues is thin-layer chromatogrphy, in which complex Preliminary separation and purification of Gls. mixtures are necessary. In 1978, Harth et al published a direct thin-layer chromatography system for separating an aliquot of the total lipid extract. The three successive solvent systems used are: A, chloroform; B, chloroform-methanol-water (C:M:W, 70:30:4 V/V/V);C, Chloroform-methanol-0.25% KC1 (60:35:8, V/V/V). Satisfactory...

The classic method for determining gangliosides (Gls) species in tissues is thin-layer chromatogrphy, in which complex Preliminary separation and purification of Gls. mixtures are necessary. In 1978, Harth et al published a direct thin-layer chromatography system for separating an aliquot of the total lipid extract. The three successive solvent systems used are: A, chloroform; B, chloroform-methanol-water (C:M:W, 70:30:4 V/V/V);C, Chloroform-methanol-0.25% KC1 (60:35:8, V/V/V). Satisfactory chromatogram has been obtained by this rapid and simple procedure, but it has not been popularized. Why is it not popularized? We think it is because the deep color of the crude extract seriously disturbs the determination of sialic acid (SA). In addition, it is difficult to control the volume of the sample applied onto the thin Plate. We adopted a silica gel coated Plate with crude tissue lipid extract in chloroform-methanol directly applied to it. The plate is developed with Harth's solvent A and B, and located with resorcinol-HCl reagent. The scraped silica gel containing Gls was eluted with methanol and chloroform-methanol mixtures respectively. The eluents are centrifugalized and dried with flow of nitrogen. The residue thus obtained is redissolved in C:M(1:1)and applied on the high-performance thin-layer chromatography (HPTLC) plate with SA concentration as parameter. The plate was developed with the solvent C:M:0.15% CaCl_2 (60:40:9, V/V/V),thus Gls were well separated from each other as well as from the other lipids. The improved method has the advantage of removing the interference caused by colored materials and sparing the HPTLC Plates used in comparison with the Harth's method. The procedure has omitted Folch's partition, and thus results nearer to the natural state could be obtained more readily than the classic method.

组织神经节苷脂(Gls)传统的分析方法,是用薄层层析,在分析之前要先进行操作步骤繁杂的分离纯化。Harth等于1978年报告用组织粗提液直接点样于层析薄板,再以三种不同的溶剂系统展开的方法,得清晰的薄板层析图谱。它们的展开剂为:1.氯仿;2.氯仿-甲醇-水(70:30:4,V/V/V);3.氯仿-甲醇-0.25%KCl(60:35:8,V/V/V)。此法简便,但未能推广采用。根据我们的经验它未能推广的原因是粗提液颜色较深,对唾液酸测定干扰甚大,薄板上的点样量较难掌握。我们用硅胶G层析薄板(5×20厘米),将组织的氯仿-甲醇粗提液直接点样于其上,以Harth的前两种展开剂展开后,用问苯二酚显色,参考定位,刮下含Gls部分硅胶,经洗脱、离心、氮气吹干后,溶于C:M(1:1),以唾液酸含量为参数,点样于高效层析(HPTLC)薄板上,在氯仿-甲醇-0.15%CaCl_2(60:40:9,V/V/V)展开,可得良好的图谱。这一改良可去掉呈色物质,大大减少HPTLC板的用量,降低了成本,同时本法未经Folch分配,有可能获得比传统方法更为真实的结果。

A new solvent resin hydration process in low water/C4 ratio, three reactor tandem conversion system, was studied for the separation of isobutene from G fraction, according to the investigation of liquid-liquid equilibrium in ternary system. The test results provided basis for the engi-neering design. The process decreased water/ isobutene ( molar ratio) from 50.24 to 5.55, solvent/isobutene) from 13.14 to 4.51.isobutene; C4 fraction; hydration; liquid-liquid equilibrium

根据三元组液-液相平衡的研究,选择了液-液平衡相图中2~#区低水/碳四值进料的水合新工艺——三器串联转化流程,并对诸项影响因素进行了系统的条件实验,为工程设计提供了依据。新工艺比原溶剂水合法有明显改进,水/异丁烯(摩尔比)值从50.24降至5.55,溶剂/异丁烯(摩尔比)值从13.14降到4.51,因此可节约水近90%,节约溶剂65%。
