Abstract
The present invention provides a preparation method for alkylphenol polyethenoxy ether benzoate, which comprises the esterification reaction and the water washing of alkylphenol polyethenoxy ether and benzoyl chloride. The alkylphenol polyethenoxy ether and the benzoyl chloride are added and mixed in a reaction kettle in the molar ratio of 1:1.05 to 1.2 to carry out the esterification reaction for 1 to 5 hours at 80 to 230 DEG C and 1 atmospheric pressure, and then, a finished product is obtained by water washing. The alkylphenol polyethenoxy ether benzoate is a good surface active agent, and the alkylphenol polyethenoxy ether benzoate can be prepared into a plurality of high-efficiency washing agents to replace the existing organic solvent which is easy to burn, explode and pollute environment. The present invention can be used for the washing of various kinds of oil stain, and the present invention has the good value of popularization and use.
Description
The present invention relates to a kind of synthetic method of nontoxic, pollution-free, non-stimulated tensio-active agent, specifically a kind of preparation method of alkyl phenol polyoxyvinyl ether benzoate.
In industrial production, the workman often will be cleaned and overhaul by machinery equipment and component thereof that greasy filth pollutes those, in the prior art those machinery equipment of being polluted by greasy filth and component thereof being cleaned employed clean-out system is gasoline, kerosene, diesel oil, zellon and other organic solvents, or use mixed solvent behind these solvent complexes, the deficiency of its existence is that above-mentioned clean-out system all is petrochemicals, except the cost height, also have explosive, inflammable, not easy to store and the transportation, be difficult to after the use recycle, directly environment is caused severe contamination etc., also do not have good clean-out system to substitute above-mentioned organic solvent at present and be used for industrial production.
The purpose of this invention is to provide that a kind of production cost that can substitute organic cleaning solvent fully is low, environmentally safe, can be used for the preparation method of industrial alkyl phenol polyoxyvinyl ether benzoate on a large scale.
The objective of the invention is to realize in the following manner, adopt alkylphenol polyoxyethylene and Benzoyl chloride to carry out esterification and generate the alkyl phenol polyoxyvinyl ether benzoate crude product, through washing, water was made elaboration in static minute again.
The preparation method of alkyl phenol polyoxyvinyl ether benzoate of the present invention, comprise the esterification and the washing of alkylphenol polyoxyethylene and Benzoyl chloride, esterification be with alkylphenol polyoxyethylene and Benzoyl chloride with 1: the mol ratio of 1.05-1.2 adds the reactor hybrid reaction, temperature of reaction is controlled at 80-230 ℃, pressure is 1 normal atmosphere, reaction times is 2-4 hour, and static separation is removed the aqueous solution and got crude product.
The raw material alkylphenol polyoxyethylene can be that the polymerization degree is n=3-13,
The ether chain is
Alkylphenol polyoxyethylene and the alkyl phenol polyoxyvinyl ether benzoate compound that generated of Benzoyl chloride.With 70-90 ℃ of gained crude product heating, remove the aqueous solution after static and get elaboration.
The concrete preparation method of alkyl phenol polyoxyvinyl ether benzoate of the present invention is as follows:
Embodiment one
1: 1.05 in molar ratio proportioning is calculated and got the polymerization degree is that n=3-13 ether chain molecular formula is:
200 kilograms of nonyl phenol polyethenoxy ethers with molecular formula be
52.6 kilograms of input reactors of Benzoyl chloride in carry out the heated and stirred esterification, temperature of reaction is controlled at 90 ℃, pressure is 1 normal atmosphere, the reaction times is 3 hours, static 1 hour, separates and to remove the aqueous solution and get crude product.
70 ℃ of static aqueous solution of removing of nonyl phenol polyethenoxy ester benzoic ether crude product heating that reaction is generated get elaboration.
Embodiment two
1: 1.05 in molar ratio proportioning is calculated and got the polymerization degree is that n=3-13 ether chain molecular formula is:
200 kilograms of hexadecyl phenol polyethenoxy ethers with molecular formula be
49.88 kilograms of Benzoyl chlorides, drop in the reactor and heat esterification, temperature of reaction is controlled at 200 ℃, pressure is 1 normal atmosphere, the reaction times is 2 hours, static 1 hour, separates and removes the aqueous solution and get crude product.To react and generate 90 ℃ of hexadecyl phenol polyethenoxy ester benzoic ether crude product heating, and remove the aqueous solution after static to get elaboration.
The preparation method of alkyl phenol polyoxyvinyl ether benzoate of the present invention is compared with existing technology, Have that reasonable in design, technology is simple, the product applied range, can substitute fully existing inflammable, The organic solvent of explosive, easy contaminated environment, and the characteristics such as with low cost, thereby, have well Popularizing value.
