乙酸酐生产工艺及检测       

[摘要] 乙酸酐主要用于用作乙酰化剂，以及用于药物、染料、醋酸纤维制造。制取的方法是烯酮法。而化学品安全说明表是安全生产、急救不可缺少的资料，简称MSDS。在工艺的设计方面简要的介绍了高沸塔，低沸塔，成品冷凝器、冷却器 H-208、H-209，T-301残渣塔，H-301冷凝器，离心泵的选择及计算。关于检测方面主要介绍了实验室常用设备如：气相色谱仪，卡尔费休水分仪，滴定仪，光谱仪，色度仪，PH仪。

Acetic anhydride production

Molding Technology Polymer Materials Management and Logistics

 [Abstract]    Acetic anhydride used for acetylation agent, as well as for drugs, dyes, cellulose acetate manufacturing. Preparation of ketene law is. And chemical safety sheets are safe production, an indispensable first-aid information, referred to as MSDS. In the design process a brief introduction of high boiling tower, low-boiling tower, finished condenser, cooler H-208, H-209, T-301 tower residue, H-301 condenser, centrifugal pump selection and calculation . Mainly introduced for the detection of commonly used laboratory equipment, such as: gas chromatograph, Karl Fischer moisture meter, titrator, spectrometer, colorimeter, PH Miriam.
