This invention discloses a cobalt zeolite catalyst, its preparation method, and its application in the oxidation reactions of benzylamine, alcohols, and anisole sulfides, specifically relating to alcohol oxidation, amine oxidative coupling, and sulfide oxidation reactions. This invention further expands the application scope of cobalt zeolite catalysts, clarifying their suitability for the oxidation reactions of alcohols, amines, and sulfides. The catalyst is prepared via in-situ hydrothermal synthesis, and its catalytic performance can be optimized by precisely controlling pore size, cobalt species dispersion, and their existing forms. Under oxygen or air atmospheres, this catalyst can efficiently achieve highly selective oxidation of benzyl alcohols, while simultaneously promoting the oxidative coupling reactions of benzylamines and the selective oxidation reactions of sulfides. The cobalt zeolite catalyst provided by this invention has clearly defined application scenarios, mild reaction conditions, and demonstrates significant industrial application potential, providing important theoretical reference and practical direction for catalyst development in the field of green organic synthesis.

The application provides a foaming agent, a preparation method and application of the foaming agent in a natural gas well liquid discharge gas recovery process. The foaming agent comprises the following components in mass fraction: 2wt%-20wt% of a surfactant, 1wt%-20wt% of an amine oxide, 13wt%-30wt% of a carbonyl functional group-containing amine oxide, and the rest is water. The preparation method comprises the following steps: adding water into a reaction kettle, then adding the surfactant and stirring until the surfactant is completely dissolved, and then adding the amine oxide and the carbonyl functional group-containing amine oxide in sequence and stirring until the foaming agent is obtained. The foaming agent provided by the application is helpful to the formation of bubbles. In the condition of a concentration of 0.5wt%, the foam volume is sufficient, the liquid separation half-life period can well meet the standard requirement, and the foaming agent has good salt resistance. Through the introduction of the carbonyl functional group, the problem of uneven liquid film stress caused by condensate oil in the water film can be overcome, so that the foaming agent has strong oil resistance.

Using an amine oxide-type surfactant as a thickener causes a problem of a decrease in the strength of a slurry of a hydraulic composition due to mixing of bubbles. Accordingly, there is the problem that although a silicone-based antifoaming agent is added as described above, a hydrophilic thickener and a hydrophobic antifoaming agent are gradually separated after production, and performance as each of the thickener and the antifoaming agent degrades over time. Therefore, a thickener composition having excellent storage stability that maintains uniformity for a long period of time without separating the thickener and the antifoaming agent is desired.　To solve the problem, provided is a thickener composition comprising: an (A) component which is an amine oxide-type surfactant; and a (B) component which is a fatty acid glyceride.

The application relates to the technical field of amide preparation, and discloses a method for preparing amide through photocatalytic oxidation and amination. The method comprises the following steps: under visible light irradiation, a nitrogen source is reacted with a hydrocarbon compound in the presence of a photocatalyst and an additive, and after post-treatment, amide is obtained; wherein the photocatalyst is a photoactive carbazole compound; the additive comprises alkaline substances and acidic substances; and the hydrocarbon compound is selected from one or more of C3-C11 chain alkanes, C3-C11 cycloalkanes and C3-C11 alkyl-substituted aromatic hydrocarbons. According to the method, a C-C bond in a low or medium hydrocarbon compound is directly oxidized and aminated to break and synthesize chain amide or lactam through photocatalysis. The method has mild reaction conditions, avoids the use of a high-pressure mercury lamp or other ultraviolet lamps, avoids the generation of tar and coke under ultraviolet conditions, and avoids the use of a large amount of alcohol additives such as t-butyl alcohol.
