BENZYLDIMETHYLDODECYLAMMONIUM CHLORIDE - Preparation Method

Open Data Verified Data

with decanediol and dimethylamine as raw materials, under the action of high efficiency catalyst, one-step catalytic ammonia is made into tertiary amine, the crude content can reach 85%, and more than 95% pure product can be obtained by distillation. Alternatively, dodecyl bromide can be synthesized from dodecyl alcohol, reacted with dimethylamine to obtain dodecyl dimethyl tertiary amine, and finally reacted with benzyl chloride to obtain benzalkonium chloride.

BENZYLDIMETHYLDODECYLAMMONIUM CHLORIDE - Application

Open Data Verified Data

is one of the commonly used non-oxidizing bactericides in industrial circulating water treatment. Soluble in water, not affected by water hardness, easy to use, low cost, but also has the corrosion of iron metal, cleaning and stripping slime and remove the function of water odor, it is a pleiotropic agent. The use of conditions directly affect its bactericidal activity, the appropriate increase of pH value, to improve the bactericidal power is beneficial. In circulating cooling water treatment, the general dosage of 85% benzalkonium chloride and 45% 1227 is 50 ~ lOOmg/L; When used as slime stripper, the dosage is 200 ~ 300mg/L. 1227 can be used with other fungicides, such as isothiazolinone, glutaraldehyde, dithiocyanomethane, etc., can play a synergistic effect, but 1227 can not be mixed with anionic surfactants.
