选择合适的容积，一般来时反应釜标的容积都是全容积，然而真正使用的容积只有2/3，要考虑过多的液体因膨胀会产生危险的压力。

Select the appropriate volume, in general,the volume of the reaction kettle is full capacity, but the real use of thevolume is only 2/3, to consider too much liquid due to the expansion willproduce dangerous pressure.

温度压力的选择，一般来时同种材质的反应釜在温度与压力越高时，反应的壁厚盖厚以及压力表都要随之加厚与加大量程，也就是说，温度压力越大时釜就会越笨重，在操控上的舒适度就会差一些。因此在温度压力上的选择时要注意，你要用到多少度及压力时就选择多少度及多大压力的釜，不要想着越大越安全，其实生产厂家已经替我们实验猿们考虑了，比如一台5MPa的釜，厂家一般都会把安全系数放大一倍，那实际上耐压是10MPa。这样已经很安全了。

Selection of pressure and temperature,generally in the reaction kettle（新疆时时彩评测网 www.fz9jb.cn） with the same material in temperature andpressure is higher, reaction of wall thick cover thickness and pressure gaugeto subsequently thickening and increased range, that is, the greater thetemperature and pressure kettle will be more cumbersome, in control of comfortwill be poor some. Therefore in the selection of pressure and temperature tonote, you have to use the number of degrees and pressure on the choice of whatand how much pressure kettle, do not think the bigger the better, in fact,manufacturers have for us the ape who considered, such as a 5MPa kettle,manufacturers generally will magnify the safety factor of a times. Actually,that pressure is 10MPa. This is already safe.

如果只用到5MPa，非要选择一台10MPa的釜，那么生产出来后实际就是一台能耐到20MPa的釜，想一想这样是不是大材小用且用起来还很不方便。温度也一样，也不用想着为以后的反应做准备，可能等到你毕业了都没能没有机会用到更高的温度与压力，只要用在当下即可。

If only to 5 MPa, to choose a 10MPa kettle,so produced is actually a capability to 20MPa kettle, think this is notoverkill and is not convenient. Temperature is the same, do not have to thinkfor the future of the reaction to prepare, may wait until you graduate did nothave the opportunity to use a higher temperature and pressure, as long as thecurrent can be used.
