Abstract
The invention relates to a preparation method of a novel anionic surfactant alkyl diphenyl ether sulfonate. The preparation method specifically comprises the steps of: with diphenyl ether and alpha-olefin as main raw materials, in the presence of solid acid catalyst, preserving heat for 1-5 hours under the temperature condition of 80-180 DEG C to produce an intermediate product alkyl diphenyl ether, then adding an inert organic solvent and a sulfonating agent for sulfonating at 0-80 DEG C to produce alkyl diphenyl ether sulfonic acid, and adding an alkali neutralizing agent for neutralizing till the PH value is 6.5-7.5, so as to produce alkyl diphenyl ether sulfonate.
Description
Technical field
The invention belongs to chemical and make the field, be specifically related to a kind of alkyl diphenyl ether sulfonate and preparation method thereof.
Background technology
Alkyl diphenyl ether sulfonate mainly is divided into alkyl diphenyl ether monosulfonate, alkyl diphenyl ether disulfonate, two alkyl diphenyl ether disulfonate, domestic enterprise uses the whole dependence on import of these series product at present, the domestic composition problem that does not still have actual this product of solution does not have homemade goods yet and appears on the market.I address this problem by the effort more than 1 year, and the actual superior finished product of effect that synthesized.Through and external imported product relatively, surface tension when concentration 0.1%, all in the 29-31 dynes per centimeter, import substitutes fully.Product has extensive use at industrial circles such as oil production, textile printing and dyeing, latex processing.Product synthetic aspect, at present, when aromatic hydrocarbon carries out alkylation, alkylation adopts hydrochloric ether more, alkene and Fatty Alcohol(C12-C14 and C12-C18) are alkylating reagent, with preparation alkylation catalysts such as aluminum chloride and hydrochloric acid, but this method technology is loaded down with trivial details, by product is many, the catalyst treatment cost is big, and when Fatty Alcohol(C12-C14 and C12-C18) or alkene were done alkylation as alkylating reagent, also useful sulfuric acid was done alkylation catalyst, but it is big to do the catalyzer requirement with sulfuric acid, serious to equipment corrosion, and in alkylation process, easily cause the sulfonation in advance of phenyl ether, cause the alkylation difficulty, by product increases thus, and sulfuric acid sepn process complexity in the purification process after alkylation finishes takes time and effort, and sewage quantity is big.It is alkylation catalyst that the present invention adopts sulfonated styrene diethylene benzene copoly mer, has avoided the appeal problem, the alkylation quickness and high efficiency that becomes, and cleaning is a kind of very good processing method.
Summary of the invention
Goal of the invention: problem to be solved by this invention provides a kind of anion surfactant of import substitution like product, a kind of alkyl diphenyl ether sulfonate and preparation method thereof, and the present invention specifically realizes goal of the invention as follows:
(1) 1-10mol phenyl ether and 1-5mol a-alkene are dropped into the alkylated reaction still.(2) catalyst solid acid is dropped into reactor, and progressively be warmed up to 80-180 ℃, under this temperature condition, be incubated 1-5 hour, to reaction end.(3) will go up step product filtering solid acid catalyst.
(4) will go up step (3) filtrate high temperature rectifying or underpressure distillation, get 270-350 ℃ of cut, be the intermediate product alkyl diphenyl ether.(5) will go up step (4) alkyl diphenyl ether and send into the sulfonation still, again inert organic solvents be put into the sulfonation still, and progressively add the 1-10mol sulphonating agent and be incubated sulfonation 1-5 hour at 0-80 ℃ then.(6) add water 10-60% stirring in above-mentioned (5) product, static acid out divides after the layering and removes the spent acid water layer then, and oil reservoir is alkyl diphenyl ether sulfonic acid and ORGANIC SOLVENT MIXTURES.(7) the mixture decompression of above-mentioned (6) is heated up in a steamer except inert organic solvents, get the alkyl diphenyl ether sulfonic acid.(8) add water and add alkaline neutraliser 1-3mol to above-mentioned (7) gained alkyl diphenyl ether sulfonic acid and be neutralized to the mixture that pH value 6.5-7.5 gets alkyl diphenyl ether sulfonate and a small amount of insolubles.(9) above-mentioned (8) gained material is filtered, the filtering insolubles to desired content, gets light yellow finished product alkyl diphenyl ether sulfonate product to the filtrate thin up;
Effect of the present invention and benefit are:
(1) aspect synthetic technology: adopting sulfonated styrene diethylene benzene copoly mer is catalyzer, the alkylation still corrosion of having avoided sulfuric acid to bring as alkylation catalyst, and avoided production of by-products, and can remove by filter catalyzer, convenient and swift.(2) aspect economic benefit: substituted the like product of a large amount of imports, reduced the interests loss of national industry, and because the buying of production domesticization back becomes convenient, improved production and operation efficient.(3) aspect product performance: this excellent product performance, both had anti-strong acid, highly basic, properties such as inorganic salt, surface tension can reach the 29-31 dynes per centimeter when concentration 0.1%, and have remarkable emulsifying property, and cheap, and cost performance is good.Product also alternative commercially available alkylphenol polyoxyethylene, sodium alkyl benzene sulfonate, alkyl sodium sulfonate, fatty alcohol-polyoxyethylene ether in industrial circles such as oil production, textile printing and dyeing, latex processing, metal processing, surface cleaning.Aspect emulsification, dispersing property, acid-and base-resisting, inorganic salt, high-temperature behavior, be that present commercially available alkylphenol polyoxyethylene, sodium alkyl benzene sulfonate, fatty alcohol-polyoxyethylene ether etc. are wetting, the 2-10 of dispersion, emulsification class tensio-active agent doubly.When increasing substantially product stability in use and effect, reduce usage quantity significantly, reduced use cost, reduced the environmental pollution index because using tensio-active agent to cause simultaneously;
