文档编号:HG165  文档字数:14715,页数:46

 摘 要：羟基聚硅氧烷是有机硅工业的重要产品之一。目前国内主要的生产方式是传统的间歇二步法，该生产工艺及设备简单，但在合成过程中反应体系粘度变化范围过大，造成自动控制困难。从而直接导致产品质量不稳定、品质低下。此外，该工艺还存在单套装置生产能力低、能耗大等缺陷。而国外采用连续化新工艺生产羟基硅油，则可做到产品的分子量及粘度十分均一，性能优异。但其生产流程、核心控制技术均严格保密，我国无从学习和借鉴。
 对此，我们课题组对连续化制备羟基硅油的基础反应即有水条件下环硅氧烷开环聚合反应的机理、动力学模型等的前期研究基础上，设计出连续制备工艺流程，并进行详细的工艺计算和设备选型，为进一步的连续化中试装置的建设，乃至工业规模装置的建设奠定基础。

Abstract:  The hydroxide polysiloxane is one of the important products of the organic silicon industry. Currently local main traditional intermittent two footworks carry on the production, should produce the craft and equipmentses simple, but respond the system to glue one degree variety scope in synthesize process over greatly, make automatic control difficult. Cause the product quantity unsteady thus and directly, the quality is lowly. In addition, that craft still exists the single suit to place the production ability low, can consume big etc. blemish. But the foreign adoption continue the new craft  production  hydroxide polysiloxane, then can attain the product molecular weight and glue the degree very uniform, the function is excellent.But its production process, core control the technique keeps secret all and strictly, the our country have no from study and draw lessons from.
 To this, we the hydroxide polysiloxane opens the front of the mechanism, the dynamics model...etc. that the wreath comes together the reaction to expect to study the foundation under the condition that the topic set to make the foundation reaction of have the hydroxide polysiloxane continuously- have the water up, design to make to have the craft process continuously, and carry on detailed craft's compute to choose the type with equipments, for turn continuously further in the construction of try the device, is go to the industry scale to equip of construction lay the foundation.

Keywords：Hydroxide polysiloxane ; Continue ; Make of the system ; The technological design and equipmentses choose the type
