| Introduction | cyclohexanone peroxide, white or light yellow needle crystal or powder, soluble in alcohol, benzene, acetic acid, petroleum ether, acetone, insoluble in water, with strong oxidation. It is mainly used as a crosslinking agent and an initiator for the synthesis of rubber and plastics. |
| Application | used as a curing agent for hand-laid FRP products, cast and coated articles synthetic crosslinking agents and initiators for rubber and plastics. |
| production method | 1.196.3G of cyclohexanone and 30% of hydrogen peroxide were respectively cooled to below 10 °c, and the hydrogen peroxide was added to cyclohexanone under stirring, and the feed temperature was controlled to be ≤ 15 °c. Add 24ml 2mol/L hydrochloric acid at 15 ℃, control the temperature not to exceed 30 ℃, gradually solidify the material, and stir constantly to avoid caking. Add 400ml distilled water, wash and suction filter, filter cake is washed with distilled water 2~3 times, with distilled water 400ml to paste, add 10% NaOK to pH 8, suction filter, water, it was dried by pressing and air-dried to obtain cyclohexanone peroxide. 2. Preparation Method: Add freshly distilled cyclohexanone (2)980G (10mol) into enamel basin, cool to below 5 ℃ in ice bath, 28% L(10mol) of 1.2 hydrogen peroxide cooled to below 5 °c was added with stirring, and the reaction was exothermic and raised to 40 °c. After cooling to below 15 ℃, there may be crystallization. 200ml of 2mol/L hydrochloric acid was added slowly with stirring, and the reaction exothermic temperature was raised to about 30 °c. Cooling with stirring, Suction filtration, washing 2 times with 2L distilled water, then stirring into slurry with 2L water, neutralizing to pH 6 with 4% sodium hydroxide, Suction filtration, washing 2 times, air drying, compound (1) was obtained in an amount of 1.05-1.1, mp77 -79 °c, and a yield of 85%-89%.
