“…In order to obtain cationic surfactants with better properties, while resolving toxicity and biodegradability, scientists have done a lot of research [5][6][7]. Numerous studies have confirmed that the water-soluble and biodegradability could be improved by adding new polar groups such as an ether, ester, amide, polyoxyethylene chain imidazoline ring and so on into the molecular structure of a typical quaternary ammonium cationic surfactant [8][9][10][11][12].…”

A new lauryl amidopropyl trimethyl ammonium methyl carbonate with the formula CH3(CH2)10CONH(CH2)3N+(CH3)3CH3CO3− was synthesized via a high pressure process with tertiary amines and dimethyl carbonate, and its chemical structure was confirmed using 1H‐NMR spectra, mass spectral fragmentation, and FTIR spectroscopic analysis. In addition, several quaternary ammonium salts with new counterions X− (X−=HCO3−, HCOO−, CH3COO−, CH3CH(OH)COO−) were also synthesized by the ion exchange reaction of methyl carbonate quaternary ammoniums with corresponding acids. The surface activities of these compounds were measured, including surface tension (γ), critical micelle concentration and minimum surface area (Amin) at 25 °C. Adsorption and micellization free energies of these quaternary ammonium salts in their solutions showed a good tendency towards adsorption at interfaces. The antimicrobial activities are reported for the first time against representative bacteria and fungi for lauryl amidopropyl trimethyl ammoniums. It was found that the antimicrobial potency was Gram‐positive bacteria > fungi > Gram‐negative bacteria.

“…Triethanolamine (TEA)-based esterquats are potential highvalue biodegradable products used as surfactants and softening agents. There have been an increasing number of researchers who have concerned themselves with the biodegradable esterquats cationic surfactant since the beginning of the 1990s [13]. Due to the presence of the ester bond in the cationic surfactant, esterquats cationic surfactants can be degraded in the environment [8].…”

“…In addition, cationic surfactants are highly biodegradable and biocompatible because their ester bonds are easily hydrolyzed. Besides biodegradability, additional advantages such as excellent softening properties, suitability for various fabrics and simple preparation procedures, have been discovered with the use of esterquats cationic surfactants as textile softening agents [5,6,10,13,14,16].…”

In this study, estimation capabilities of the artificial neural network (ANN) and the wavelet neural network (WNN) based on genetic algorithm were investigated in a synthesis process. An enzymatic reaction catalyzed by Novozym 435 was selected as the model synthesis process. The conversion of enzymatic reaction was investigated as a response of five independent variables; enzyme amount, reaction time, reaction temperature, substrates molar ratio and agitation speed in conjunction with an experimental design. After training of the artificial neurons in ANN and WNN, using the data of 30 experimental points, the products were used for estimation of the response of the 18 experimental points. Estimated responses were compared with the experimentally determined responses and prediction capabilities of ANN and WNN were determined. Performance assessment indicated that the WNN model possessed superior predictive ability than the ANN model, since a very close agreement between the experimental and the predicted values was obtained.
