[0004] However, at present, the raw materials of alkylphenol polyoxyethylene ether acetic acid surfactants—the industrial alkylphenol polyoxyethylene ether surfactants are octylphenol, nonylphenol and ethylene oxide with branched chain structures. Alkanes are produced by condensation under the trigger of an initiator, which mainly has the following two disadvantages: (1) there are few types of hydrophobic groups and serious branching (the alkyl chains are obtained from the oligomerization of propylene or isobutylene), and the more serious the branching is, the The slower the degradation rate of alkylphenols produced during the degradation process; (2) the number of polyoxyethylenes is in a possion distribution, which is only a rough average value, and the performance of products from different manufacturers is different, which is not conducive to the use of this type of surfactant in practical application
[0006] CN 1296115A discloses the application of this type of surfactant in enhancing oil recovery, and mentions industrial nonylphenol polyoxyethylene ether as a raw material, but it also does not mention linear alkylphenol homogeneous polyoxyethylene ether acetic acid Surfactant, and it has the problem that the raw material is too single

Embodiment 1

[0073] The synthesis of embodiment 1 laurylphenol trioxyethylene ether sodium acetate

[0074] (a) Synthesis of straight chain lauryl phenol

[0075] method one:

[0076] Add 5 mol of phenol into a three-neck flask equipped with a mechanical stirrer, a thermometer and a constant pressure dropping funnel, add 5 mL of boron trifluoride ether solution at room temperature, and after mixing thoroughly, add 1 mol α-deca Diene, after the dropwise addition, the reaction temperature was controlled to be 50° C. and maintained for 8 hours. After the reaction was completed, excess phenol was distilled off, and then distilled under reduced pressure to collect high boiling range fractions, which were linear laurylphenols, with a yield of 90%.

[0077] Method Two:

[0078]Add 1 mol of phenol into a three-necked flask equipped with magnetic stirring, raise the temperature to 70°C, add 1.05 mol of lauroyl chloride dropwise, continue the reaction until no gas is released after the addition, s...

Abstract

The invention belongs to high efficiency surface activating agent field, in particular relating to nonionic to anion linear chain alkylphenol homogeneous polyoxy divinyl ether etic acid surface activating agent and the preparation method and use. The liner chain alkylpheno is preceded by a series of reactions to form nonionic to anion surface activating agent substance. The unique molecular structure decides the surface activating agent has good water solubility and hardwater resistance, high efficiency foaming capability and excellent temperature tolerance, the surface activating agent has lower critical micelle concentration and surface tension, the critical tension can reach to super low (10 to 3mN / m) with various different oiliness crude oil. The invention has good prospect in industry washing, spinning and three-times oil extraction and other fileds, which can be used as effective oil displacement agent in three-times oil extraction. Comparing with traditional fork chain alkylphenol homogeneous polyoxy divinyl ether etic acid surface activating agent, the invention has stable performance and the biological degradation is easier. The chemical structure formula of the surface activating agent is as drawing.

Description

technical field [0001] The invention belongs to the field of high-efficiency surfactants, and in particular relates to a nonionic-anionic linear alkylphenol homogeneous polyoxyethylene ether acetic acid surfactant and a preparation method and application thereof. Background technique [0002] Alkylphenol polyoxyethylene ether surfactants, as a class of nonionic surfactants with excellent performance, are widely used in daily chemical and industrial fields as emulsifiers, fungicides, defoggers and antifreeze agents; There are phenylene ether oxygen bonds in its molecules, so its chemical properties are very stable, especially it has the characteristics of temperature resistance and salt resistance, but the application of nonionic surfactants is limited due to the influence of cloud point. [0003] And alkylphenol polyoxyethylene ether acetic acid surfactant, as a non-ionic-anionic surfactant, on the basis of adhering to the advantages of alkylphenol polyoxyethylene ether surf...
