- Double electron type polymerizable surfactant monomer, and preparation method and applications thereof
-
The invention discloses a double electron type polymerizable surfactant monomer. A preparation method comprises following steps: 1, epoxy chloropropane and a long chain tertiary amine are subjected toring-opening reaction in a hydrochloric acid solution so as to obtain an intermediate EPT; 2, EPT and N-dimethyl aminopropyl methacrylamide are subjected to quaterisation so as to obtain a finial product. The double electron type polymerizable surfactant monomer, acrylamide, acrylic acid, and 2-acrylamido-2-methylpropane sulfonic acid are subjected to polymerization, drying, crushing, and sievingat room temperature so as to obtain a polymer thickening agent powder; the polymer thickening agent powder is prepared into a 0.3wt% solution which is taken as a fracturing fluid. The preparation method is friendly to the environment; cost is low; yield and purity are relatively high; the hydrophobic associated polymer solution based on the monomer possesses excellent viscoelasticity and temperature resistance and salt resistance, so that the fracturing liquid prepared from the monomer is capable of solving technical problems in the prior art that conventional hydrophobic associated polymer fracturing liquid cost is high, and sand suspension capacity is poor.

- Guanidyl long chain gemini quaternary ammonium salt and preparation method thereof
-
The invention discloses a guanidyl long chain gemini quaternary ammonium salt and a preparation method thereof, wherein long chain gemini quaternary ammonium salts and long chain alkyl tertiary amines are added into a solvent, are added with epichlorohydrin drop by drop in 40-90 DEG C, and obtain intermediate products by reacting after being added drop by drop; and the intermediate products are added into alcohol, are added with long chain guanidine drop by drop in 30-110 DEG C after being uniformly stirred, and react for 4-48h after being added drop by drop to obtain guanidyl long chain gemini quaternary ammonium salts. The guanidyl long chain gemini quaternary ammonium salt and the preparation method thereof adopt open loops of epoxide and bimolecular nucleophilic reactions, wherein H+ and epoxy groups are easy to combine in an open ring reaction of the epoxide, and enable tertiary amines which are used as nucleophilic reagents to be more rapid when attacking carbonium ions. Quaternary ammonium surfactants are in a system in a second reaction, are used as a surface active agent to greatly promote quaternization, and improve reaction speed as a whole. The guanidyl long chain gemini quaternary ammonium salt and the preparation method thereof are simple in reaction process, clear in target products, less in accessory substances and concise in purification process, and further reduces cost.
