Unit 1 Production of DrugsAbout 5000 antibiotics have already been isolated from microorganisms，but of these only somewhat fewer than 100 are in therapeutic use. It must be remembered，however，that many derivatives have been modified by partial synthesis for therapeutic use;some 50，000 agents have been semisynthetically obtained from户lactams alone in the last decade. Fermentations are carried out in stainless steel fermentors with volumes up to 400 m3. To avoid contamination of the microorganisms with phages etc. the whole process has to be performed under sterile conditions. Since the more important fermentations occur exclusively under aerobic conditions a good supply of oxygen or air(sterile)is needed. Carbon dioxide sources include carbohydrates，e. g. molasses，saccharides，and glucose. Additionally the microorganisms must be supplied in the growth medium with nitrogen-containing compounds such as ammonium sulfate，ammonia，or urea，as well as with inorganic phosphates. Furthermore，constant optimal pH and temperature are required. In the case of penicillin G，the fermentation is finished after 200 hours，and the cell mass is separated by filtration. The desired active agents are isolated from the filtrate by absorption or extraction processes. The cell mass，if not the desired product，can be further used as an animal feedstuff owing to its high protein content.关于5000抗生素已经分离出的微生物，但其中只有不到100有些治疗使用。

Unit 13 Sterile ProductsSterile ProductsSterile products are dosage forms of therapeutic agents that are free of viable microorganisms. Principally，these include parenteral，ophthalmic，irrigating preparations. Of these, and parenteral products are unique among dosage forms of drugs because they are injected through the skin or mucous membranes into internal body compartment. Thus，because they have circumvented the highly efficient first line of body defense，the skin and mucous membranes，they must be free from microbial contamination and from toxic components as well as possess an exceptionally high level of purity. All components and processes involved in the preparation of these products must be selected and designed to eliminate，as much as possible，contamination of all types，whether of physical，chemical，or microbiologic origin.Preparations for the eye, though not introduced into internal body cavities，are placed in contact with tissues that are very sensitive to contamination. Therefore，similar standards are required for ophthalmic preparations).Irrigating solutions are now also required to meet the same standards as parenteral solutions because during an irrigation procedure，substantial amounts of these solutions can enter the bloodstream directly through open blood vessels of wounds or abraded mucous membranes. Therefore，the characteristics and standards presented in this chapter for the production of large-volume parenteral solutions apply equally to irrigating solutions. Sterile products are most frequently solutions or suspensions，but may even be solid pellets for tissue implantation. The control of a process to minimize contamination for a small quantity of such a product can be achieved with relative ease. As the quantity of product increases，the problems of controlling the process to prevent contamination multiply. Therefore，the preparation of sterile products has become a highly specialized area in pharmaceutical processing. The standards established，the attitude of personnel，and the process control must be of a第13 单元无菌产品无菌产品无菌产品是不含微生物活体的治疗剂剂型，其主要包括非肠道用的、眼用的和冲洗用的制剂。

Distillation columns are vertical, cylindrical vessels containing devices that provide intimate contacting of the rising vapor with the descending liquid.蒸馏塔是垂直的，可以提供给上升的蒸汽与下降的液体直接接触的圆柱形容器控制设备。

This contacting provides the opportunity for the two streams to achieve some approach to thermodynamic equilibrium.这种接触为两个流体实现热力学平衡提供了机会。

Depending on the type of internal devices used, the contacting may occur in discrete steps, called plates or trays, or in a continuous differential manner on the surface of a packing material.取决于使用的内部设备的类型，能使接触出现分离的叫塔板或者分流塔盘，或者是在一个能连续差分方式的包装材料的表面上。

The fundamental requirement of the column is to provide efficient and economic contacting at a required mass-transfer rate.蒸馏塔的根本要求，是为客户提供高效和经济的同时要与必要的质量传输速率相联系。

Individual column requirements vary from high vacuum to high pressure, from low to high liquid rates, from clean to dirty systems, and so on.个人塔的要求各不相同从高真空至高压力，从低到高的液率，从清洁到不清洁的系统，等等。

High-Performance Zeolite NaA Membranes on Polymer-Zeolite Composite Hollow Fiber Supports聚合物—沸石复合中空纤维载体上的高性能NaA型沸石膜NaA型沸石膜具有亲水性，并且在有机溶液除水中表现出高度选择性，特别是在醇类的脱水中，此过程也是生产生物燃料过程中必要和造价昂贵的一步。

沸石膜过去常用晶种法来合成。

在载体上排种被认为是获得高性能沸石膜的一个关键性因素。

许多排种方法曾在报刊上发表过。

然而，对于合成高渗透蒸发性的沸石膜而言，当中没有一个方法是完美的，主要是因为使晶种在载体表面形成一致排布的困难性。

另一方面，虽然沸石膜依附在大直径（12mm）陶瓷管的应用在亚欧地区已经商业化，但是陶瓷管直径大且价格贵，另外膜的通率低。

大直径与低通率结合在一起，就会导致模块尺寸较大。

不久之前，我们曾报导过一个新的排种方法，浸涂——涂抹沉积，这是在陶瓷中空纤维载体中获得高性能NaA型沸石膜的一种非常有效的方法。

这种基于高性能陶瓷中空纤维的沸石膜可预期明显地减小模块尺寸，但是生产陶瓷中空纤维的花费仍在考虑之中，另外，排种过程仍然困难。

这里，我们介绍一个新策略：利用聚合物—沸石复合中空纤维作为载体。

把沸石晶体作为晶种嵌入聚合物中空纤维中供沸石膜生长，同时它们也把沸石膜“锚”在载体上，从而增加沸石膜的附着力。

从而，一个单独且通常很复杂的排种过程就此可以省略了。

一个非常均匀的晶体排布可以很容易获得，因此，高度可再生的沸石膜就可以连续不断地制备了。

复合中空纤维可以很容易生产，通过在中空纤维剂条成型之前把沸石晶体混进复合原料里即可，并且这样可以降低成本。

聚醚砜—沸石复合中空纤维载体是通过把包含NaA型沸石粉末的聚醚砜溶液纺成中空纤维原丝的方法来制备的，根据文献记载，所得产物之后在水中冲洗并在60℃下干燥。

复合中空纤维载体的表面及横截面通过扫描电子显微镜来检查。
