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.
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.
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.
