연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

Disclosed herein are methods for the preparation of a free-flowing, storage-stable fatty acid metal salt product by forming a reactive admixture comprising (a) an unsaturated fatty acid glyceride feedstock; and (b) from about 1 mol to about 3 mol of at least one monovalent metal hydroxide or at least one divalent metal hydroxide; and heating the admixture to a temperature at which said fatty acid glycerides saponify to form fatty acid metals salts; wherein said monovalent metal is potassium; and wherein said divalent metal is selected from the group consisting of calcium, copper, magnesium and zinc. The fatty acid glycerides may be saponified in an atmosphere in which the partial pressure of oxygen has been reduced by an amount effective to provide an improvement in storage stability until a free-flowing, storage-stage product is obtained, or prior to saponification, the fatty acid glycerides may blended with a stabilizing oil that promotes storage stability, or both. Storage stable metal salts of unsaturated fatty acids prepared by the inventive methods are also disclosed.
