| | Dodecyldimethylbenzylammonium chloride Usage And Synthesis |
| 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. | | Flammability and Explosibility | Not classified | | Synthesis | 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. | | References | [1] Russian Chemical Bulletin, 2014, vol. 63, # 11, p. 2445 - 2454
