反應(yīng)結(jié)晶是指氣體與液體或液體與液體之間進(jìn)行化學(xué)反應(yīng)產(chǎn)生難溶或不溶固相物質(zhì)的過(guò)程。反應(yīng)結(jié)晶法可以使一些易生成沉淀的物質(zhì)與其它化合物分離，從而達(dá)到純化的目的。
反應(yīng)結(jié)晶過(guò)程有高選擇性的特點(diǎn)，常用于產(chǎn)品的分離提純。
Reaction crystallization refers to the chemical reaction between a gas and a liquid or liquid or liquid to produce insoluble or insoluble solid matter. Reactive crystallization can make some easily precipitated substances separate from other compounds, so as to achieve the purpose of purification. The reaction crystallization process is characterized by high selectivity and is often used in the separation and purification of products.
反應(yīng)結(jié)晶的幾個(gè)影響因素：飽和度，溫度，混合均勻度，攪拌強(qiáng)度，物質(zhì)純度。
普通結(jié)晶罐自動(dòng)化程度低，兩相或多相物料混合，為了達(dá)到好的混合效果，攪拌強(qiáng)烈，容易產(chǎn)生大量細(xì)晶，當(dāng)細(xì)晶小于1μm 時(shí)，細(xì)晶會(huì)有團(tuán)聚現(xiàn)象，即范得華力會(huì)起作用。因此產(chǎn)品粒度分布過(guò)寬，粘度變大，洗滌量增加，離心后晶間包裹的殘液量相對(duì)增大，導(dǎo)致產(chǎn)品純度低，另外操作靠經(jīng)驗(yàn)和簡(jiǎn)單的指標(biāo)控制，不同班次工人操作有差異?？寇?chē)間管理難解決問(wèn)題，導(dǎo)致產(chǎn)品批間差異大，粒度分布不均勻，產(chǎn)品質(zhì)量不穩(wěn)定；從綜合成本考慮，間歇操作繁瑣，動(dòng)力消耗高，不適合批量產(chǎn)品的生產(chǎn)。
Several factors affecting reactive crystallization: degree of saturation, temperature, mixing uniformity, agitation strength, and material purity. The ordinary crystallization tank is low in automation, and when the two phase or multiphase materials are mixed, In order to achieve good mixing effect, the stirring process can be strong and easily producing a lot of fine grains. When the fine grain is less than 1 m, the fine grain will reunion, the Van der Waals force will come into effect. Therefore, when the product size distribution is too wide, the viscosity becomes larger, the washing capacity increases, and the residual liquid content between the crystals increases relatively after centrifugation, the low purity of the product will be caused. In addition, the operation is controlled by experience and simple indicators, and there are differences in the operation of workers in different shifts. The difficulty to solve problems by workshop management results in large differences among the products, uneven distribution of grain size, and unstable quality of products. Considering the comprehensive cost, the intermittent operation is tedious, the power consumption is high, and it is not suitable for the production of mass products.
