Description
Technical Field
The invention relates to the technical field of fine chemical engineering, in particular to a di-tertiary amine bisamide sulfonic acid type surfactant, and a preparation method and application thereof.
Background
The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
The surfactant is a compound which can obviously change the interface state of a solution system by adding a small amount of surfactant, and is an amphiphilic molecule formed by two groups or chain segments with opposite hydrophilic and hydrophobic properties at two ends of the same molecule and connected by chemical bonds. Surfactants have good emulsifying, defoaming, wetting, washing, disinfecting, softening, antistatic properties and the like, and are growing in industrial and civil applications due to their special properties.
Low foaming surfactants are surfactants that exhibit low foaming properties during spray cleaning or during other use. The low foam is set primarily for the purpose of meeting production requirements. In the production of certain products, the production of foam is adversely affected and therefore low or no foam surfactant products are desired. For example, non-foaming or low-foaming industrial detergents are used as metal cleaners, metal degreasers, plastic cleaners, etc., and more typical uses are spray cleaners, spray degreasers, high pressure water rinse additives, ultrasonic cleaners, etc.
For example, the use of low foaming surfactants in metal cleaning has been described in the prior art as the use of dow chemical low foaming surfactants in metal cleaning, including polyethers, alkyl glucosides (APG) and alkyl polyether glucosides (AEG); in addition, the preparation method of the grease-based amino acid salt series surfactant is disclosed as follows: firstly, grease and amino acid salt with the molar ratio of 1 (1.5-5) or fatty acid and amino acid salt with the molar ratio of 1 (1.05-1.5) are added into a normal pressure reactor with a heating, stirring and temperature regulating device; secondly, adding a catalyst, fully stirring, heating to control the reaction temperature at 130-190 ℃, reacting for 2-8 h, finally cooling the reaction temperature to 60-90 ℃, adding a neutralizing agent, and adjusting the pH value to 7-8 to obtain the product.
The inventor finds that most of the current researches on low-foaming surfactants concentrate on the aspects of surfactant formula and composition, the research on the function of the low-foaming surfactant by using a single-component surfactant is not extensive, and the developed varieties are few.
Secondly, at present, the development types and the number of the sulfonate surfactants are not large, the price is expensive, the wide application of the sulfonate surfactants is limited, and particularly, the varieties developed in the aspect of low-foaming surfactants are less. In addition, the inventor finds that the existing surfactant still has the disadvantages of low foaming performance, poor emulsifying performance and complex preparation process technology and method.
