Abstract
The invention discloses a kind of synthetic method is simple, raw material is easy to get, and reaction step is few, the preparation method of the high Diallytrisin of finished product content, comprising the following steps: 1) sodium hydrosulfide for taking 50 parts of NaHS that 0.6 mol is made with 100 parts of water is spare;2) 1000ml there-necked flask is taken, is added 280 parts of pure water, Bunte salt is made in 300 parts of the dodium thiosulfate of 1.2mol, 92 parts of the chloropropene of 1.2mol;3) 30 ~ 50 DEG C of temperature control stir lower a dropping step 1) prepared by 150 parts of sodium hydrosulfide of 0.6 mol, decompose Bunte salt;4) 2-6 hours are stood, up to crude product after layered shaping;5) step 4 gained crude product is put into rectifying still, carries out rectification under vacuum, 90 ~ 110 DEG C of bottom temperature of control collects 62 ~ 64 DEG C/100Pa of temperature, obtains Diallytrisin product.
Description
Technical field:
Present invention relates particularly to a kind of preparation methods of Diallytrisin, belong to chemical technology field.
Background technique:
Diallytrisin be a kind of yellow liquid, have disgusting smell, 112~120 DEG C of boiling point
(2133Pa) or 95~97 DEG C (667Pa) or 70 DEG C (133Pa), not soluble in water and ethyl alcohol is miscible in ether.Main application is
Medicine intermediate, food additives, feed addictive.The preparation method of existing Diallytrisin be using S and Na2S by
2:1 synthesizes Na2S3, and then Na2S3 is reacted with allyl chloride by 1:2;Since the vulcanized sodium of synthesis is based on Na2S3 and to contain
The mixture of Na2S, Na2S2, Na2S4 etc., crude product ingredient is more miscellaneous after processing, main peak content about 40%.
Summary of the invention:
In view of this, raw material is easy to get the present invention provides a kind of synthetic method is simple, reaction step is few, and finished product content is high
Diallytrisin preparation method.
To achieve the above object, the technical solution adopted by the present invention are as follows:
A kind of preparation method of Diallytrisin is prepared by following raw material through special process: pure water 280
Part, 300 parts of the dodium thiosulfate of 1.2mol, 150 parts of sodium hydrosulfide of 92 parts of the chloropropene of 1.2mol, 0.6 mol.
A kind of preparation method of Diallytrisin, comprising the following steps:
1) sodium hydrosulfide for taking 50 parts of NaHS that 0.6 mol is made with 100 parts of water is spare;
2) 1000ml there-necked flask, 280 parts of pure water of addition, 300 parts of the dodium thiosulfate of 1.2mol, the chloropropene of 1.2mol are taken
92 parts, Bunte salt is made;
3) 30 ~ 50 DEG C of temperature control stir lower a dropping step 1) prepared by 150 parts of sodium hydrosulfide of 0.6 mol, decompose
Bunte salt;
4) 2-6 hours are stood, 86 parts of crude product to obtain the final product after layered shaping, content 82.5%;
5) rectification under vacuum is carried out with 100ml three-necked flask, shunt head, 90 ~ 110 DEG C of bottom temperature of control collects temperature 62 ~ 64
DEG C/100Pa, obtain the Diallytrisin product of 66 parts of contents 92%.
The beneficial effects of the present invention are: synthetic method is simple, raw material is easy to get, and production cost is low, and reaction step is few, and finished product contains
Amount is high, is suitble to large-scale production.
Specific embodiment:
To further elucidate this programme, the preferred embodiments of the invention are described combined with specific embodiments below, these
Description is intended merely to further illustrate advantages of the present invention, rather than limiting to the claimed invention.
