Intro
Anionic
surfactants. Low production costs , performance, and therefore widely used,
is the largest amount of synthetic household detergent surfactants , also
produce some magnesium , calcium salts and organic amine salts such as
triethanolamine . Calcium dodecylbenzenesulfonate has excellent emulsifying
properties, is used in the preparation of various pesticides mixed emulsifier
important part. By benzene and α- olefin in three aluminum chloride catalyst
condensation, condensation of liquid caustic washing , washing the recovery of
benzene was evaporated under vacuum distillation to obtain refined benzene .
Then sulfonation with fuming sulfuric acid , lime neutralization ( in ethanol
with 2 times the amount ) , to obtain calcium dodecylbenzenesulfonate . Acrylic
emulsion as anionic emulsifiers .
Alkylbenzene sulfonate is a yellow oil
which was purified hexagonal or rhomboid form strong lamellae. With micro-
toxicity, has been identified as safe international security organization
chemicals, cleaning utensils in fruit and application . LAS in detergents used
in the largest amount , the use of large-scale automated production , low
prices. Used in detergents have branched structure benzene sulfonate (ABS) and
straight- chain structure (LAS) are two biodegradable branched structure is
small, pollute the environment , and straight -chain structure readily
biodegradable , biodegradability can be greater than 90% , the small degree of
environmental pollution
Use
Oxidation, foaming power, detergency , easy to complex with various additives , low cost synthesis process maturity , extensive applications , it is very good anionic surfactant . Sodium alkylbenzenesulfonate dirt particle , protein dirt and oily dirt decontamination significant effect on the natural fiber wash effect on particulate soil is preferred, the washing detergency with the rise of temperature increase , the protein stain effects than non -ionic surfactant , and rich foam
