| titleOfInvention | With the method for the propionic acid synthesized tricyclodecenyl esters spices of load-type solid acid catalyst |
| abstract | The invention provides a kind of synthetic method of tricyclo decenyl propionate spices; oil coke by-products dicyclopentadiene and propionic acid is adopted to be raw material; electrophilic addition is passed through under effect under supported solid acid catalysis; directly carry out acetylization reaction one step and prepare tricyclo decenyl propionate crude product; add a small amount of propionic anhydride guard catalyst simultaneously, prevent and a small amount of moisture generation hydrolysis reaction of containing in material.Then reclaim propionic acid to apply mechanically, obtain tricyclo decenyl propionate finished product through neutralization &washing, rectifying.This method raw material oil coke by-products source is easy to get, and reaction conditions is gentle, and reaction conversion ratio is high, and technics comparing is easily implemented, and produce three wastes discharge amount in production process few, product yield is greatly improved, and belongs to process for cleanly preparing.In product, there are three fragrant and sweet rings of blue or green perfume (or spice)-anise [5,2,1,0 simultaneouslyn 2.6 ] content of-3-decene-9-alcohol acetic ester reaches more than 92%, product green grass or young crops-banksia rose gas is pure, fine and smooth, soft, present invention also offers tricyclo decenyl propionate perfume synthesis special purpose device. |
