| titleOfInvention | A kind of preparation method of Diallytrisin |
| 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. |
