Embodiment

[0030] (1) Preparation of intermediates:

[0031] Take 0.3mol of thionyl chloride (20ml) and 10ml of ether in a three-necked flask, and add 0.1mol of sodium m-carboxybenzenesulfonate NaO three times 3 S-C 6 h 5 -(CH 2 ) n Add COOH within 1 hour, stir the reaction at room temperature until almost no hydrogen chloride and sulfur dioxide gas escape, add 3 drops of N,N-dimethylformamide with a rubber dropper, a total of about 0.15ml, at 60°C Stir the reaction for 4h, add 40ml of diethyl ether to dilute after cooling, add 60ml of n-hexane, cool to -25°C and place for 12h, filter out the precipitated light yellow crystal, and dry to obtain the intermediate.

[0032] The diethyl ether used in the above preparation process can also be replaced by benzene, dichloromethane or toluene, and the molar ratio remains unchanged.

Abstract

The invention relates to an alkylaryl sulfonate type hyperbranched polymer surface active agent and a preparation method thereof. The surface active agent is an anionic-nonionic surface active agent. The preparation process is that organic solvent and thionyl chloride are added in a flask, then sulfobenzoic acid monosodium salt is added to be reacted until hydrogen chloride and sulfur dioxide gas are not escaped, DMF is added, stirring reaction is performed under the temperature of 60 DEG C, the organic solvent is added for dilution after cooling, a certain amount of normal hexane is added, and after the temperature is cooled to below 25 DEG C, a filtered and separated pale yellow crystal is placed so as to obtain a midbody after being dried; and hydroxyl-terminated hyperbranched polymer which is one third of molar weight of the midbody is placed in a reactor, methylene dichloride is added under the room temperature, triethylamine is added to serve as catalyst, stirring reaction is performed, and after reaction is ended, evaporation, extraction and filtration are performed to obtain the alkylaryl sulfonate type hyperbranched polymer surface active agent. The alkylaryl sulfonate type hyperbranched polymer surface active agent has higher surface activity and lower CMC (Critical Micelle Concentration) and good emulsion stability, facilitates biodegradation, and is environmental protection.

Description

technical field [0001] The invention relates to an active agent used for solubilizers, emulsifiers, daily chemicals and tertiary oil recovery, in particular to an alkyl aryl sulfonate type hyperbranched polymer surfactant and a preparation method. Background technique [0002] Hyperbranched polymers have become a research hotspot in recent years due to their abundant terminal functional groups, low melting point, good rheological properties, good solubility, high reactivity, relatively simple synthesis methods and internal cavities in the molecule. Hyperbranched polymer surfactants have multiple hydrophilic (lipophilic) groups, which makes hyperbranched polymer surfactants have more diversity and higher surface activity than general surfactants; secondly, hyperbranched polymer surfactants The surface active polymer has a large number of end groups, and most of them are hydrophilic groups. The lipophilic groups are wrapped inside the molecule to form an lipophilic cavity, and...
