Properties and stability
Easily soluble in methylene chloride, acetone, soluble in benzene, carbon tetrachloride, ethyl acetate, ethanol, slightly soluble in gasoline, insoluble in water. Gradually decomposes when exposed to heat. This product is non-toxic.
Storage method
Should be stored at low temperature. The shelf life is 6 months.
Synthesis method
Add accelerator M into the morpholine aqueous solution, add sodium hypochlorite dropwise at 23-56°C to perform an oxidation reaction to obtain a semi-finished product, and then filter, wash, and dry to obtain the finished product. Raw material consumption (kg/t) accelerator M (97%) 840 morpholine (60%) 700 chlorine (95%) 478 caustic soda (40%) 4251 sulfuric acid (95%) 1170
Purpose
It is used as a post-effect rapid vulcanization accelerator with long scorching time and good operation safety. Easy to disperse, no blooming, slight discoloration, especially suitable for natural rubber and synthetic rubber containing alkaline furnace black. The vulcanized rubber has excellent physical and aging properties. Mainly used in the manufacture of tires, inner tubes, rubber shoes, tapes, backing rubber for retreading tires, etc.
