Abstract:
More and more attention has been paid to the phase transfer catalyst because it can significantly reduce the reaction conditions and improve the reaction yield. Rutzen Horst invented and patented the synthesis of N-(2-hydroxy) long-chain alkyl-N,N,N-trimethylammonium chloride [1-3]. The authors have synthesized N-(dehydroabietyloxy-2-hydroxy) propyl-N,N,N-trimethylammonium chloride [4]. In this paper, long-chain alkyl glycidyl ether was obtained by the reaction of fatty alcohol and epichlorohydrin, and N-(3-long-chain alkoxy-2-hydroxy) chloride was obtained by the reaction with trimethylamine hydrochloride under mild conditions. Propyl-N,N,N-trimethylammonium. It is found that these substances have good phase transfer catalysis. The nomenclature and abbreviations of the four products synthesized in this paper are as follows: N-(3-dodecyloxy-2-hydroxy) propyl-N,N,N-trimethylammonium chloride (DPAC), N-(3-decaethoxy-2-hydroxy) propyl-N,N,N-trimethylammonium chloride (TPAC), N-(3-decaethoxy-2-hydroxy) chloride propyl-N,N,N-trimethylammonium (HPAC), N-(3-decanoxo-2-hydroxy) propyl-N,N,N-trimethylammonium chloride (OPAC)

Abstract:
The monomer 3-[N,N-dimethyl-[2-(2-methylpropan-2-enoyloxy)] ethyl] Ammonium] propane -1-sulfonic acid internal salt (DMAPS), acrylic acid (AA) with ionic liquid 1-ethyl-3-methylimidazolium dicyandiamide ([EMI][DCA]) in the next step of UV irradiation, the ionic gel was prepared. The structure of the ionic gel was characterized by Fourier transform infrared spectroscopy (FTIR), and the thermal properties were characterized by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), the mechanical properties were tested by electronic universal testing machine, and the strain and pressure sensing properties of ion gel were tested by digital multimeter and LCR digital bridge. The results showed that the synthesized ionic gel exhibited high transparency, high tensile strength (elongation at break about 650%) and high ionic conductivity (about 1.31 mS/cm); the cyclic tensile and compression tests show that the ionic gel has good elasticity. As a resistance sensor, the ion gel shows high sensitivity and stability for different strain sensing, the capacitive sensor constructed by the ion gel can effectively sense the pressure.

Abstract:
A cationic Diester surfactant, N,N,N-trimethyl -2, was synthesized by using anhydrous glyceryl trimethyl ammonium chloride, a reactive epoxy intermediate, 3-bis (stearyloxy) propyl ammonium chloride (CDESA), to replace the traditional refractory surface active softener, such as the current domestic still in a large number of the use of dioctaalkyl dimethyl ammonium chloride (D1821). In this paper, the aerobic degradation performance of CDESA was studied: the living sludge in the natural environment was used as the source of microorganisms, diluted with river water, cultured and domesticated to test the degradation time and half-life, the aerobic degradation performance was compared with that of d1821. The results show that the half-life of CDESA is 3 days, which is easy to degrade, while the half-life of D1821 is 7 days, which is more difficult to degrade. The biodegradation performance of CDESA is better than D1821.
