Patent DE-3928382-A1 (DE)
Inventor: WEISS ALBRECHT DR
IPC: C12P7/64
Filed: 1989-08-28
Abstract: Disclosed is a method of preparing monoglycerides which are substantially free of di- and triglycerides. In this method, glycerine is reacted with a fatty acid in the presence of lipase with the aim of obtaining largely diglyceride-free monoglycerides even when the yield of acid is high. This is achieved by virtue of the fact that monocarboxylic acids with 12-24 C-atoms which are solid under the conditions of the reaction are suspended in the form of powder with a specific surface area of more than 0.5 m<2>/cm<3> in a molar excess of glycerine and allowed to react in the presence of a monoglyceride lipase to more than 80 % of the theoretical yield relative to the monocarboxylic acid.

Title: Coupling for fluid pipes - with valves on each half and with flushing action during coupling movement
Inventor: FICKEL HANS-CHRISTIAN
IPC: F16L37/30
Filed: 1990-12-21
Abstract: The two pipe ends (2,3) are each fitted with valves (15,18,46,51) which shut off the ends when the connection is opened.
