Technical Field
The invention belongs to the technical field of oil industrial production, and particularly relates to a hydrogenation modification process of epoxy fatty acid methyl ester and saturated fatty acid methyl ester containing hydroxyl.
Background
At present, anionic surfactant fatty acid methyl ester sulfonate MES and nonionic surfactant fatty acid methyl ester ethoxylate FMEE commonly used in the daily chemical industry are mainly synthesized by adopting saturated fatty acid methyl ester. The saturated fatty acid methyl ester is synthesized by using unsaturated fatty acid methyl ester containing carbon-carbon double bonds as a raw material through hydrogenation reaction, and the oxidation resistance stability of the fatty acid methyl ester is improved while the carbon-carbon double bonds are eliminated.
Epoxy fatty acid methyl esters are generally prepared by reacting unsaturated double bonds in fatty acid methyl esters with peroxy organic acids in the presence of catalysts, and because they contain epoxy groups, they are often used as intermediates for the production of chemicals having a variety of industrial uses. Although the iodine value in the product index of the epoxy methyl ester is reduced and the degree of unsaturation of a carbon chain is also reduced, the ring opening of the epoxy fatty acid methyl ester influences the synthesis of a target product, so that no published research data reports an industrial process for preparing a surfactant product by using the epoxy fatty acid methyl ester as a production raw material.

Further, the epoxy fatty acid methyl ester is a fatty acid methyl ester containing an epoxy group having at least one three-membered ring,
preferably, the epoxidized fatty acid methyl ester is any one of epoxidized soybean oil methyl ester, epoxidized palm oil methyl ester, epoxidized cottonseed oil methyl ester, epoxidized rapeseed oil methyl ester, epoxidized oleic acid methyl ester, epoxidized castor oil methyl ester and epoxidized hogwash oil methyl ester, or a combination of at least two of them.
Preferably, the epoxy value of the epoxidized fatty acid methyl ester is 3 to 8%.
Preferably, the BET specific surface area of the catalyst used in the hydrogenation process is 100-200m2The pore volume is 0.4-0.5mL/g, the compaction density is 700-3The average grain diameter is 2.0-3.0 mm; the mass content of the metallic nickel in the catalyst is 15-25%; the average size of the alumina is 1.0-2.0 mm.
In order to achieve the second purpose, the invention adopts the following technical scheme:
saturated fatty acid methyl ester containing hydroxyl is prepared by the hydrogenation modification process of the epoxy fatty acid methyl ester.
Compared with the prior art, the method has the advantages that although saturated fatty acid methyl ester can be obtained only by one more epoxy fatty acid methyl ester synthesis process, the finally obtained saturated fatty acid methyl ester containing hydroxyl has special efficacy, so that higher economic benefit exists in the whole surfactant production process.
Detailed Description

The hydrogenation modification process has the following process key points:
1. hydrogenation catalyst:
the catalyst has effective component of metal nickel and carrier component of alumina. Wherein, the metallic nickel is granular, and the mass content in the catalyst is 15-25%, preferably 20%. The alumina is solid particles with an average size of 1.0-2.0 mm.
The BET specific surface area of the catalyst is 100-2The pore volume is 0.4-0.5mL/g, the compaction density is 700-3The average particle diameter is 2.0-3.0 mm.
2. A hydrogenation reactor:

internal pressure of the reactor: 2-4 Mpa.
The temperature of the reaction mass is 100-150 ℃.
The residence time of the reaction mass is 1-4 hours.
In the process, the reaction temperature of the hydrogenation process is low, so that the chain scission of methyl ester in epoxy fatty acid methyl ester can be avoided to generate fatty acid and methanol; the catalyst carrier alumina is an acidic carrier, which is beneficial to ring opening of an epoxy group and improvement of the reaction rate; the obtained saturated fatty acid methyl ester containing hydroxyl has higher saturation, the iodine value of the product is lower than 0.5, and the epoxy value is lower than 0.1%.
The following illustrates an example of the synthesis of a hydroxyl-containing saturated fatty acid methyl ester by the process of hydrogenating and modifying an epoxy fatty acid methyl ester:
example 1
Adding 200 g of epoxy palm oil methyl ester (epoxy value is 3.5%) and 10 g of catalyst into 500ml of high-pressure reaction kettle with an electric stirring device, a measuring thermometer and a measuring kettle in sequence, stirring and heating to 90 ℃, introducing high-purity hydrogen, maintaining the pressure of 3MPa, continuously heating to 145 ℃, reacting for 1.5 hours, stopping, and filtering the catalyst to obtain the refined saturated palm methyl ester containing hydroxyl.
Example 2
200 g of epoxidized soybean oil methyl ester (epoxy value is 3.5%) and 30 g of catalyst are sequentially added into a 500ml high-pressure reaction kettle with an electric stirring device, a measuring thermometer and a measuring kettle, the temperature is raised to 90 ℃ by stirring, high-purity hydrogen is introduced, the pressure is maintained at 3MPa, the temperature is continuously raised to 130 ℃, the reaction is stopped after 2.5 hours, and the catalyst is filtered to obtain the refined saturated soybean oil methyl ester containing hydroxyl.

remarking: sulfonation process: the method refers to a general sulfonation reaction process containing hydroxyl, which is different from a sulfonation process for synthesizing a-sulfo saturated fatty acid methyl ester salt, wherein the saturated fatty acid methyl ester needs a complex sulfonation process such as sulfonation-aging-reesterification-bleaching-neutralization and the like.
Ethoxylation process: the method refers to a general ethoxylation process containing hydroxyl, and is different from a fatty acid methyl ester insertion or mosaic type fatty acid methyl ester ethoxylation compound process, a special catalyst is needed, and only a general ethoxylation catalyst is needed, such as sodium hydroxide, potassium hydroxide, sodium methoxide and the like.
The saturated fatty acid methyl ester containing hydroxyl obtained by the epoxy fatty acid methyl ester hydrogenation modification process can obtain the surfactant with a structure different from the conventional structure by a relatively simple process for synthesizing the surfactant.
