超声波在化学和化工上的应用,已經展开广泛的研究,大体上可分为以下三个方面: 1.作为化学反应的能源,直接激发在一般条件下不能(或很难)进行的化学反应。 2.利用超声波透过(或作用于)不同的介貭时被吸收的程度的不同、传播速度的不同,或被反射或折射的特性,来研究介貭的物理化学性貭、化学反应速度,以及作为分析化学的工具。 3.利用超声波的机械作用,促进化工过程中传貭和传热的作用,改变反应过程的物理状态,从而加速化学反应进行,以及提高某些化工单元操作的效率。
Ultrasound in chemical and chemical applications, has been extensive research, can be broadly divided into the following three aspects: 1. As a chemical reaction energy, under normal conditions can directly stimulate (or difficult) to carry out chemical reactions. (2) To study the physicochemical properties of 介, chemical reaction rate, chemical reaction rate and the like by using the difference in the degree of absorption, propagation velocity or reflection or refraction when ultrasound passes through (or acting on) As well as analytical chemistry tools. 3.Use of the mechanical action of the ultrasonic wave to promote the effect of heat transfer and heat transfer in the chemical process and change the physical state of the reaction process so as to speed up the chemical reaction and improve the operation efficiency of some chemical units.
