Synthesis and Characterization of N,N-Dimethyl Dodecyl-(4-Vinyl Benzyl) Ammonium Chloride

Abstract

In this investigation, dodecyl dimethyl (vinylbenzyl) ammonium chloride is synthesized through the reaction between 4-vinylbenzyl chloride and N,N-dimethyl-dodecylamine. This resultant compound is characterized by H-NMR, FTIR, TGA, and antibacterial assays. It is found that this chemical reaction is achievable. Moreover, it is also observed that this compound have good thermal ability, and its decomposition temperature is 207°C. The antibacterial tests prove that it have excellent antibacterial abilities against E.coli and S. aureus. Therefore, these results are demonstrated that it can be applied in bulk modification of polymers for better antibacterial and mechanical properties.

Antimicrobial, anti‐inflammatory, and antioxidant evaluations of ammonium and phosphonium salts based on poly(vinylbenzyl chloride‐co‐acrylonitrile)

“…The main weight loss was in the range of 280–490°C, losing ~61% of its weight, due to polymer chains decomposition and the cyclization of the nitrile groups and the evolution of gases like HCN and NH3 52 . Notably, heating until 800°C left a residue of 24% which might be due to the carbonization of copolymer segments 53 …”

“…52 Notably, heating until 800 C left a residue of 24% which might be due to the carbonization of copolymer segments. 53 The initial decomposition temperature of ammonium salt of (KH2) is found at 174 C which is lower than raw copolymer (265 C). This may be attributed to the hydrophilicity of TEA, which leads to the loss of 10% of its weight.…”

In-situ Polymerization of N-(3-aminobenzyl)-N, N-dimethyl-N-dodecyl Ammonium Bromide on Glassy Carbon Electrode for Estradiol Detection

“…The strong peaks at 2925 and 2855 cm -1 are the stretching vibration of methyl and methylene groups in the alkyl side chain of monomer molecule. The 1627.83 cm -1 peak is attributed to the amine group on the benzene ring, and the 1460.96 cm -1 peak is due to N-CH 3 vibration absorption; The 1120.99 cm -1 peak is ascribed to C-N stretching vibration; The adsorption of β-CH 2 connecting on N + appears at 1044.11 cm -1 and that of benzene ring at 653.90 and 583.36 cm -1 [19][20][21].…”

Quaternary ammonium salts substituted by 5‐phenyl‐1,3,4‐oxadiazole‐2‐thiol as novel antibacterial agents with low cytotoxicity

“…Due to excellent antibacterial activities, quaternary ammonium salts (QAS) were used as antiseptics, disinfectants, medical apparatus and instruments, and other clinical applications, such as preoperative disinfection of unbroken skin and trauma . Mang alkyl‐QAS, dialkyl‐QAS, QAS‐iodine, benzalkonium chloride (BZK), chlorhexidine acetate (CA), and BQAC (bisquaternary ammonium compounds, such as dequalinium chloride) have been invented and received increasing attentions as antibacterial agents . In particular, long‐chain alkyl‐QAS compounds show unsurpassed antibacterial effect.…”
