Surfactant-s-development-history
1.Red oil (also known as Turkey red oil), a product of sulphur acidification of castor oil (anion surfactant), was first synthesized in 1875 by German company badenaniline soda, the first synthetic surfactant used in the textile and leather industries. During the first world war, German research succeeded in producing alkyl naphthalene sulfonates from naphthalene, propanol or butanol with smoke sulfuric acid, which could be used instead of soap, thus saving the vegetable and vegetable oil used in making soap. Alkyl naphthalene sulfonate is widely used today because of its poor cleaning ability, but it has good wetting and penetration capacity and is not affected by hard water or acidic solution. In 1936, with the development of petrochemical industry, the first research in the United States was successfully made into alkyl benzene sulfonate from benzene and kerosene. Later, as a result of adding various additives and improving production technology, the synthetic detergent with alkyl benzene sulfonate as the main component was superior to soap in application performance and cost, and began to be widely used in production and life. Since then, the proportion of synthetic detergents in total washing supplies has been increasing year by year. In 1982, the output of synthetic detergents in the world reached 28Mt, which has surpassed that of soap and continued to increase. The research and production of surfactant represented by synthetic detergent has developed rapidly and become an important chemical production department. There are several thousand varieties of surfactants.
2.China's surfactant and synthetic detergent industries started in the 1950s, but developed rapidly despite a late start. In 1995, the total amount of washing articles reached 3.1 million tons, ranking second only to the United States in the world. The production of synthetic detergent increased from 400,000 tons in 1980 to 2.3 million tons in 1995, a net increase of 4.7 times, and the annual average growth rate was more than 10%. According to the forecast of Chinese authorities, the total amount of washing products will reach 3.6 million tons in 2000, among which the synthetic detergent will reach 655,000 tons. The surfactant varieties with a yield of over 10,000 tons include: Linear alkyl benzene sulfonate (LAS), fatty alcohol polyoxyethylene ether sodium sulfate (AES), fatty alcohol polyoxyethylene ether ammonium sulfate (AESA), sodium lauryl sulfate (K12 or SDS), nonylphenol polyoxyethylene ether (TX - 10) (10), peregal O and diethanolamide (6501), stearic acid, glycerin monoester, lignin sulfonate, heavy alkyl benzene sulfonates, alkyl sulfonate (petroleum sulfonate), diffusion agent NNO, dispersant MF, alkyl polyether (PO/EO copolymer), fatty alcohol polyoxyethylene (3) ether (AEO - 3), etc.
