The alkyl glycoside is a novel green surfactant which is raised in the 90 s 20 th age and is a mixed product obtained by losing one molecule of a hemiacetal suspected group and a fatty alcohol suspected group of natural renewable resources glucose under the catalysis of acid. The alkyl glycoside has the characteristics of low surface tension, no cloud point, adjustable HLB value, strong wetting power, strong detergency, rich and fine foam, strong compatibility, no toxicity, no harm, no stimulation to skin, rapid and thorough biodegradation, obvious synergistic effect and the like, and can be compounded with any type of surfactant, so the alkyl glycoside is widely applied as a green surfactant.
In the preparation process of the alkyl glycoside, the alkyl glycoside is prepared by mixing and gelatinizing glucose and fatty alcohol, and then performing dehydration and catalytic reaction. The alkyl glycoside generally needs to be decolored and bleached when the color is dark, and a certain stirring speed is needed in a general bleaching device due to the high-concentration alkyl glycoside which has high viscosity and poor fluidity, but a lot of foams are easily generated at an excessively high speed, so that the decoloring efficiency is reduced, and a defoaming device is needed for auxiliary production.
The defoaming method which is most widely applied at present is a thermal defoaming method, but in the existing thermal defoaming method, severe scaling in a heater is easily caused, so that the defoaming efficiency is greatly reduced, the energy consumption is increased, the decoloring efficiency is influenced, and the preparation efficiency of alkyl glycoside is reduced.
