specific Embodiment approach 1

[0025] Specific embodiment one: the structural formula of the high-temperature and salt-resistant naphthol derivative quaternary ammonium salt foaming agent of the present embodiment is:

[0026]

[0027] where R=C n h 2n+1 , n=10, 12, 14, 16 or 18, X is halogen. Named FS-n.

specific Embodiment approach 2

[0028] Specific embodiment two: the preparation method of the high-temperature and salt-resistant naphthol derivative quaternary ammonium salt foaming agent described in specific embodiment one, carry out according to the following steps:

[0029] 1. Add solvent I to the container, then add N-acetyl-(1-naphthyloxy)-N,N-dimethylethylenediamine and haloacetylalkylamine, wherein N-acetyl-(1 The molar ratio of -naphthyloxy)-N,N-dimethylethylenediamine to haloacetylalkylamine is 1:(1~6), heated to 100℃~160℃ and stirred for 20h~48h to obtain crude product;

[0030] 2. The crude product obtained in step 1 was rotary evaporated to obtain a white solid;

[0031] 3. After the white solid is recrystallized by solvent II, a high-temperature and salt-resistant naphthol derivative quaternary ammonium salt foam is obtained.

specific Embodiment approach 3

[0032] Specific embodiment three: the difference between this embodiment and specific embodiment two is that the solvent I in step one is a mixed solution of acetonitrile and ethanol, a mixed solution of toluene and ethanol, a mixed solution of chloroform and water, methanol and dichloro A mixed solution of methane or petroleum ether; others are the same as in the second embodiment.

Abstract

The invention relates to a surfactant foaming agent as well as a preparation method and application thereof, in particular, a high-temperature-resistant salt-tolerant naphthol derivative quaternary ammonium salt foaming agent as well as a preparation method and application thereof. According to the high-temperature-resistant salt-tolerant naphthol derivative quaternary ammonium salt foaming agentas well as the preparation method and application thereof, excellent foaming performance can be kept under the conditions of high temperature, and the presence of inorganic salt and the like, in complex environments. The structural formula of the foaming agent is shown in the specifications, wherein R=CnH2n+1, and n=10, 12, 14, 16 or 18; and X is halogen. The preparation method comprises the following steps of: reacting N-acetyl (1-naphthoxy)-N, N-dimethyl ethylenediamine with haloacetyl alkylamine to obtain a crude product; and carrying out rotary evaporation and recrystallization to obtain the foaming agent. The half-life period of the foaming agent can reach 60 hours, and the foaming agent can resist high temperature and inorganic salt and can be applied to the fields of disinfection, oil extraction, washing, drug sustained release and corrosion prevention.

Description

technical field [0001] The present invention relates to surfactant foaming agent and its preparation method and application. Background technique [0002] Quaternary ammonium salt surfactants have attracted widespread attention due to their high surface activity, good emulsifying properties, bactericidal properties and foaming properties, and they are widely used in fields such as disinfection, oil recovery, washing, drug slow release and antisepsis. In recent years, the application of surfactants as foaming agents has developed rapidly. [0003] At present, most of the common foaming agents are sulfonate surfactants and a variety of surfactant compounds. For example, a high-temperature-resistant foaming agent disclosed by the Chinese patent with the publication number CN110078865A can withstand high-temperature environments, carbon dioxide and oxygen conditions, but its half-life is 140min, which is shorter and less stable. Foam performance in complex environments. Cont...
