properties and stability
it is stable under normal temperature and pressure.
storage method
sealed packaging in plastic barrels. store in a cool and dry place. moisture-proof, heat-proof, sun-proof, and not stored together with toxic and polluting chemicals. keep away from fire and heat sources.
synthesis method
1. add glycerin to the reaction kettle, preheat to 60°c, then add oleic acid and a catalyst amount of sulfuric acid, heat to reflux under reduced pressure, dehydrate for 4 hours, cool, neutralize with 5% na2co3 aqueous solution, and reduce pressure the product is obtained by dehydration.
