设计原则

工艺生产的第一要素必须是安全第一，所以在所做的任何有关工业设计的计划，无论是反应设备，储物设备，运输设备，都必须在考虑是否安全的前提下。这也是为什么在物料衡算后，选择设备前需要去进行热量衡算。

在密封容器中，温度、压力等和安全息息相关，当反应温度过高时，需要考虑容器材质是否经受的住高温，还需要考虑在容器中进行的反应是否会有气体放出，考虑反应釜内的压力安全问题，此时决定反应是否能在密封容器中进行。此外还要考虑排出的气体是否有毒，是否能直接排放到大气中，并为废气选择合适的吸收溶剂。

在安全问题以外，还要考虑到整个设计的可行性，可操作性，并尽可能的节约成本，将产品的收益最大化。在设备选择完毕后，安装设备的问题也需要考虑。除了安全外，设备布置的前提还要考虑方便施工，方便修理，方便清洗的问题。文献综述

以上原则作为设计标准，以求达到安全而优异的工艺设计。

Design Project: Process Design of 30ton Acetyl Feruloyl Chloride with an Annual Output.

Ferulic acid (ferulic acid), chemical name 4-hydroxy-3-methoxyphenylacrylic acid, is a phenolic acid of variety plants, with polysaccharides and proteins combined into the cell wall skeleton. The toxicity of ferulic acid is very low, and its pharmacological activity is also reflected in some specific aspects. Now at least found that ferulic acid has the pharmacological functions are as follows: anti-platelet aggregation and thrombosis; anti-tumor; removal of nitrite, oxygen free radicals, nitroso nitro; anti-bacterial anti-inflammatory; anti-mutation; increase immune function; Sperm motility and exercise [1].

Studies have shown that ferulic acid has a strong antioxidant activity and has a strong scavenging effect in many groups, such as hydrogen peroxide, hydroxyl radicals, superoxide radicals, nitroso nitro groups. In addition to scavenging free radicals, ferulic acid also regulates human physiological functions, inhibits free radicals, promotes the elimination of free radicals, such as Kayallam and Kawabatta et al. “ Ferulic acid can greatly increase glutathione Peptidyl transferase and quinone reductase activity, inhibition of tyrosinase activity [2]. ” Therefore, ferulic acid can be processed as a natural safe antioxidant [3] and free radical quencher [4] to use. China is rich in traditional Chinese medicine resources, which angelica is also very common, and the method that extract ferulic acid from angelica is simple and safe. Due to the low toxicity of ferulic acid, and some countries have approved it as a food additive, it can be believed that it and its derivatives will have broad prospects in the food industry application.

There are few studies on the antioxidant properties of ferulic acid. Researchers also hope to exert their advantages through their characteristics. However, because of the poor fat solubility of ferulic acid, it is difficult to penetrate through the biofilm. So that its application in the field of food or medicine and other areas is limited, so scholars have put their eyes on the research of ferulic acid derivatives’ fat soluble. Xin Jiaying [5] has also obtained vitamin E ferulic acid ester by biocatalytic method, and has achieved good effect in the oxidation of edible oil. Pham Van Hung [6] has synthesized starch ferulic acid ester Ferulic acid, which has better solubility and oxidation resistance, is likely to be developed as a new functional food; by alcoholysis of ester exchange method, Li Dongming [7] synthesized ferulic acid glucose Esters and ferulic acid xylitol, which plays a certain effect in fruit and vegetable antioxidant.来.自>优:尔论`文/网www.youerw.com
