Dodecyldimethylbenzylammonium chloride Chemical Properties,Usage,Production

Chemical Properties

White fine crystalline powder

Uses

Benzyldimethyldodecylammonium chloride, a quaternary ammonium compound (QAC), is a cationic surfactant that shows antimicrobial activity against Gram-negative bacterium Pseudomonas fluorescens. It can be used as a:

corrosion inhibitor.
synergist to increase the toxicity of the pesticide, indoxacarb against various pests.
model for benzyltrialkylammonium salts to study the thermal degradation pathway of benzyl QACs.

Uses

Quaternary ammonium composition to treat herpes, pseudomonas, staph, hepatitis and other infectious diseases.

Definition

ChEBI: Benzododecinium chloride is the organic chloride salt of benzododecinium. It has antiseptic and disinfectant properties, and used as a preservative in eye drop formulations. It has a role as an antiseptic drug, a disinfectant, an antifouling biocide and a surfactant. It is a quaternary ammonium salt and an organic chloride salt. It contains a benzododecinium.

General method: Dodecyldimethylbenzyl ammonium chloride is synthesized by aqueous phase alkylation reaction using dodecyldimethyl tertiary amine and benzyl chloride as raw materials. The specific steps are as follows: Dodecyldimethyl tertiary amine (6 mmol) and benzyl chloride (6 mmol) are dissolved in water (2-3 mL), and the mixture formed is stirred and reacted at 60-95°C for 0.3-4 hours. Upon completion of the reaction, the solvent was removed by vacuum evaporation. The resulting residue was purified by silica gel column chromatography using chloroform-methanol (10:1, v/v) as eluent or further purified by recrystallization methods. The specific reaction conditions, yields and physicochemical parameters of the quaternary ammonium compounds 1a-g, 2a-c and 5a-c are detailed in Table 3. 1H NMR spectral data of the products are listed in Table 5.
