Sulfuric Acid → HCID 22709185, compound

Participants

Reaction Steps

To a mixture of propylene trimer (504 parts by weight (pbw)) acrylonitrile (232 pbw), and phenothiazine (0.4 pbw) is added 85% sulfuric acid (510 pbw) at 40°-45° C. over a period of one hour. The reaction is held at this temperature for an additional four hours, cooled and the upper layer (unreacted olefin, 95 pbw) separated. The lower aqueous layer is decanted into ice water (1500 pbw) and toluene (250 pbw) added. The upper organic layer is washed twice with 100 pbw portions of water, then with 20% sodium carbonate solution (35 pbw) dried over anhydrous sodium sulfate (40 pbw) and evaporated under vacuum to give the title product as a liquid residue (575 pbw).
