Fatty alkyl dimethyl benzyl quaternary ammonium salt synthesis method

The invention discloses a fatty alkyl dimethyl benzyl quaternary ammonium salt preparation method, which comprises: carrying out a salt formation reaction on fatty alkyl dimethyl tertiary amine and abenzyl halide in an organic solvent at a temperature of 30-70 DEG C, wherein R in the fatty alkyl tertiary amine is C6H13-C22H45, the halogen in the benzyl halide is chlorine, bromine or iodine, and the organic solvent is one or a plurality of materials selected from methanol, ethanol, n-propanol, isopropanol, acetone and acetonitrile. According to the present invention, the yield of the preparation method is high, and can reach more than 90%; the purity is high, and can achieve more than 99%; the water content is low; the product has good appearance and simple post-treatment effect; and the method can reduce the energy consumption, and is suitable for industrial production.

DENTAL ORAL COMPOSITION

A dental composition for oral use, containing a phosphorylated saccharide (a), a polyphosphoric acid and/or a salt thereof (b), and a cationic bactericidal agent (c), wherein a ratio of a total amount of the phosphorylated saccharide (a) and the polyphosphoric acid and/or a salt thereof (b) contained to an amount of the cationic bactericidal agent (c) contained, i.e. {(a)+(b)}/(c), is from 0.05 to 20 in a weight ratio. The dental composition for oral use of the present invention can be suitably used for an oral cavity cleaning agent, including dentifrice agents such as a paste dentifrice agent, a powder dentifrice agent, and a liquid dentifrice agent, a mouse-wash agent, a troche, a tablet, a cream, an ointment, a bonding agent, a mouth spray, a coating agent to tooth surface or a dental prosthetic, a hypersensitive inhibitor, a therapeutic agent for periodontal diseases, that is applied to a periodontal pocket, wet tissue for oral cavity care, an oral refreshing agent, chewing gum, or a gargling agent, or the like.

Preparation of benzalkonium salts differing in the length of a side alkyl Chain

Benzalkonium salts are widely used as disinfectants, biocides and detergents, among a variety of other applications. The cationic surface-activity of these salts determines their potential to act as a biocide on both target and non-target organisms. In this study, a quick synthesis of a complete set of the benzalkonium salts differing in the length of an alkylating chain (from C2 to C20) is described. Moreover, their 1H-NMR, HPLC-MS, TLC and HPLC analysis were recorded.
