Embodiment 1

[0022] A kind of rosin ester alcohol ether type quaternary ammonium salt surfactant, its general structural formula is as follows:

[0023]

[0024] In the formula, the molecular weight n of polyethylene glycol PEG is any one of 200, 400, 600, 1000, 2000, 4000, and in the formula, R is methyl CH 3 , Ethyl CH 2 CH 3 , Ethanol CH 2 CH 2 Any one of OH.

[0025]

Embodiment 2

[0027] A kind of method of rosin base alcohol ether type quaternary ammonium salt surfactant, it is characterized in that, what adopt is one-pot reaction: the first step, rosin and polyethylene glycol react and generate rosin polyethylene glycol monoester, the second In the first step, the hydroxyl group in the rosin polyethylene glycol monoester reacts with epichlorohydrin to generate an intermediate, and in the third step, the intermediate reacts with triethylamine hydrochloride to generate the product rosin base alcohol ether type quaternary ammonium salt surfactant . Synthesis includes the following steps:

[0028] Weigh rosin and polyethylene glycol 400 with a molar ratio of 1:1 and pour them into a 500mL four-necked flask, and then add an appropriate amount of zinc oxide (the amount of zinc oxide accounts for about 0.1-0.2% of the mass of rosin) as a catalyst, Heat to 230-280°C to make it fully react, and when the acid value drops to about 10, the reaction is basically ...

Embodiment 3

[0035] The synthesis process is similar to Example 2, polyethylene glycol 400 can be replaced by polyethylene glycol 600, the molar ratio of rosin to polyethylene glycol 600 is 1: (1-1.1), for example, the ratio is selected as: 1:1, 1:1.05, 1:1.1.

Abstract

The invention discloses an abietate alcohol ether type quaternary ammonium salt surface active agent. The general structural formula is as follows: the molecular weight n of polyethylene glycol (PEG) in the formula is any one in 200, 400, 600, 1000, 2000 and 4000, and in the formula, the R is any one in methyl CH3, ethyl CH2CH3, and ethanol base CH2CH2OH. The invention also comprises a preparation method of the surface active agent. The method comprise that a one-pot method is adopted, rosin and polyethylene glycol are subjected to esterification to form rosin polyethylene glycol monoester, hydroxide radical in the polyethylene glycol is subjected to etherification through epoxy chloropropane, and an epoxy group and tertiary amine hydrochloride are quaternized to obtain the abietate alcohol ether type quaternary ammonium salt surface active agent. The critical micelle concentration of prepared surface active agent is 0.1-0.3 mmol/L, and the range of surface tension is 37-39.5 mN/m. Molecules contain nonionic functional groups and cation functional groups, and the abietate alcohol ether type quaternary ammonium salt surface active agent is a novel functional environment-friendly surface active agent.

Description

technical field [0001] The invention relates to a functional green surfactant and a preparation method thereof, in particular to a rosin ester alcohol ether type quaternary ammonium salt surfactant and a preparation method thereof. Alcohol ether type quaternary ammonium salt cationic surfactant introduces ether bond and alcohol hydroxyl group on the basis of the original long-chain alkyl quaternary ammonium salt structure, so that the surfactant not only has softness, antistatic, emulsification, disinfection and sterilization, etc. In addition to performance, it also has the characteristics of high water solubility and high surface activity. Background technique [0002] Surfactants are composed of non-polar lipophilic hydrocarbon chains and polar hydrophilic groups, and have both lipophilic and hydrophilic amphoteric properties. The unique properties of surfactants make them widely used in various fields such as washing, textiles, medicine, food, and pesticides. At presen...
