一些需要加压的有机合成反应,通常在不锈钢压力釜或玻璃封管中进行。但是不锈钢压力釜操作不方便,反应物用量大,又不能直接观察反应过程中的现象。用玻璃封管时,虽然反应物用量可小些,但搅拌效果差,其最大的弱点是不能进行在指定压力下的充气加压化学反应。在研究有机金属化合物的反应中,我们设计了在低压下(5kg/cm~2左右)能进行微量化学反应的玻璃反应器。该反应器制作容易,操作简便,能避氧、避水,并可透过有机玻璃挡板直接观察反应现象(结构如图所示)。反应瓶可制成不同的容量(10～10ml),按需要调换
Some organic synthesis reactions that require pressurization are usually carried out in stainless steel autoclaves or glass closures. However, stainless steel autoclave operation is not convenient, large amount of reactants, but also can not directly observe the reaction process. Glass sealed with a tube, although the amount of reactants can be smaller, but the mixing effect is poor, the biggest weakness is that under the specified pressure can not be under inflation and pressure chemical reaction. In the study of organometallic compounds, we designed a glass reactor that can perform microchemical reactions at a low pressure (about 5 kg / cm ~ 2). The reactor is easy to manufacture, easy to operate, can avoid oxygen, avoid water, and can directly observe the reaction phenomenon through the plexiglass baffle (the structure is shown in the figure). The reaction bottle can be made of different capacity (10 ~ 10ml), according to the need to change
