摘　　要：通过加热将水由液态变为饱和水蒸气,破坏了H2O分子间的氢键,使氢原子核裸露在外,具有类似质子的作用具有极高的能量,攻击非水化磷脂中的金属离子,使磷脂酸与二价金属离子解离,脱除大豆毛油中非水化磷脂。先将毛油进行水化脱胶,去除水化磷脂,得到水化脱胶油,将水化脱胶油加热至110℃,搅拌速度90r/min,通入压力0.14MPa的饱和水蒸气,水蒸气量为油量的2%,通气时间50min,脱胶油中的磷含量为17.9mg/kg,为工业化生产提供理论依据。Water can be changed from liquid to saturated steam by heating method,which results in the destroy of hydrogen bonds among H2O molecules and the exposure of hydrogen atomic nuclei to function as the protons for attacking metal ions in non-hydrated phospholipids.The non-hydrated phospholipids can be removed from crude oil through the separation between phosphatidic acids and divalent metal ions.The optimal removal process of non-hydrated phospholipids was based on hydration degumming of crude oil for the removal of hydrated phospholipids,heating of hydrated degummed oil to 110 ℃,stirring at 90 r/min,introduction of 2%（on the basis of oil amount） saturated steam pressure at 0.14 MPa allowed to proceed for 50 min.Under the optimal conditions,the phosphorus content in degummed oil was 17.9 mg/kg.This method can provide a theoretical basis for industrial production.
