Description
Technical field
The invention belongs to the fine chemicals synthesis technical field, relate to the compound method of organic thioether, refer more particularly to the compound method of asymmetric thioether.More detailed, the present invention relates to 2-hydroxyethyl n-octyl thioether (keeping away worm alcohol) compound method.
Background technology
Keep away worm alcohol and be a kind of novel little poison (being close to nontoxic), insect repellent efficiently, mosquito, fly, reptile, ant, bedbug etc. are had efficient repellent action, can in office that personnel concentrate, restaurant, family, garden, use.In addition, it also is a kind of nonionogenic tenside commonly used, can be used as antiwear additive and is added in the lubricating oil, and still a kind of antagonist is used for agricultural, and is slow with farm crop severe deformities and growth that relieving herbicide causes.
At present, do not see bibliographical information in China as yet about keeping away synthesizing of worm alcohol.External synthetic main method of keeping away worm alcohol has reduction reaction, substitution reaction, permutoid reaction and addition reaction method.
1 reduction reaction
(1) simple substance bromine reduction [Derzhinskii A R; Chizhov O S; Prilezhaeva EN.Functional sulfur-containing compounds.Part 4.Synt-hesis ofchloro (bromo) alkyl sulfones by oxidative halogenation of hydroxyalkylsulfides and sulfoxides using hydrogen peroxide-halogen acid mixture [J] .Izvestiya Ak ademii Nauk SSSR; Seriya; Khimich-eskaya, 1982, (5): 1116-1123.]
Derzhinskii etc. keep away worm alcohol with the preparation of simple substance bromine reduction hydroxyethyl n-octyl sulphoxide, and reaction equation is:
This method yield is lower, is merely 26%, and is raw material with the hydroxyethyl n-octyl sulphoxide, is difficult for obtaining.With the simple substance bromine reduction side reaction takes place easily, sulfoxide can be generated hydroxyethyl n-octyl sulfone by the bromine oxidation.
(2) LiAlH
4Method [Derzhinskii A R; Chizhov O S; Prilezhaeva E N.Oxidativechlorination of 2-hydroxyethyl alkyl sulfides and 2-hydroxyethyl alkylsulfoxides [J] .Organosulfur Compounds; 1977, (4): 775-778.]
A.R.Derzhinskii etc. are that reductive agent has prepared and keeps away worm alcohol with the lithium aluminum hydride, and reaction formula is following:
In the experiment to make reaction vessel, to containing C with there-necked flask
8H
17SCH
2COOC
2H
5Anhydrous ether solution in dropwise add LiAlH
4Anhydrous ether solution, controlled temperature is at 5~10 ℃, then heated and boiled 40min.Reaction mixture is used MgSO earlier
4Drying is carried out underpressure distillation then and is promptly got product.
This method reaction is simpler, easy and simple to handle, and condition is also gentle.But raw material is difficult for obtaining, severe reaction conditions, and product yield is also very low.
2 substitution reactions [Sokobwski A.Chemical structure and thermodynamics ofamphiphile solutions.1.Solubility of alkylthiooligooxyethylene glycolsin water [J] .The Journal of Physical Chemistry; 1989,93 (25): 8223-8226.]
Adam Sokolowski is a raw material with octyl mercaptan and ethylene chlorhydrin, and prepared in reaction obtains keeping away worm alcohol in sodium methoxide solution, and reaction equation is following:
Reaction is homogeneous reaction under the condition that methyl alcohol exists, and reaction raw materials also obtains easily, and product yield is higher, but carries out in the homogeneous phase for making to be reflected at, be in a large number methyl alcohol with an organic solvent, the solvent recuperation power consumption is big, product postprocessing with separate purify inconvenient.
3 permutoid reactions [Malievskii A D.Exchange reaction of oxiranes with β hydroxyalkyl sulfides; Selenides, amines, and phosph-ines [J] .RussianChemical Bulletin; 2000,49 (4): 579-587.]
This method is to be that feedstock production is kept away worm alcohol with 2-alkyl hydroxyethyl n-octyl thioether and oxyethane, and reaction equation is following:
R=Me,Ph,CH
2OPh
The characteristics of this method are to remove to keep away worm alcohol and the generation of epoxy compounds no coupling product, and reaction is generally carried out in autoclave, is solvent with the chlorobenzene, and temperature of reaction is generally 150 ℃, no heat effect.But because this reaction is reversible reaction, so raw material reaction is incomplete, reaction belongs to high-temperature high-voltage reaction, can not satisfy the requirement of national energy-saving and emission-reduction.And the material thioether that uses also is difficult for obtaining.
4 addition reactions
(1) 1-octene method [Hiroaki K, Izumi T.Preparation of sulfides from olefinsand mercaptans [P] .JP:2002121182,2002-04-23.]
This method has been synthesized under catalyst action with 1-octene and mercaptoethanol and has been kept away worm alcohol.The reaction equation of this method is following:
The investigator has attempted three kinds of catalyzer: the hydroxide aqueous solution of triethylamine, sodium methylate and benzyl trimethyl ammonium carries out catalysis to reaction, and the result finds that the triethylamine catalytic effect is best.This method belongs to green economy type reaction, but raw material 1-octene relatively costliness be difficult to obtain, prospects for commercial application is little in China.
(2) epoxyethane method [Chlebicki J; Cichacz Z.The kinetics of oxiranereaction with alkanethiols in the presence of basic catalysts [J] .International Journal of Chemical Kinetics; 1988,20 (5): 387-395.]
Epoxyethane method is to be that raw material reacts under the sodium Metal 99.5 effect and makes product with oxyethane and octyl mercaptan.Reaction equation is following:
The advantage of this method is that raw material sources are wide, obtain easily, but this method by product is more, and yield is not high, and uses sodium Metal 99.5 danger higher.
