摘要:
The invention relates to a process for the preparation of an aqueous solution or suspension of a beta -lactam nucleus and application thereof. The aqueous solution or suspension of the beta -lactam nucleus is prepared by process wherein an enzymatic deacylation of a beta -lactam compound, which compounds comprises a beta -lactam nucleus with a side chain coupled to it via an amide bond and which deacylation reaction is carried out in a mixture of water and an organic solvent and which deacylation leads to a beta -lactam nucleus and a carboxylic acid, is carried out at a pH value of between 2 and 6 so that the carboxylic acid is extracted in situ to the organic solvent.

The present invention provides an adhesive composition for optical disks comprising (A) a radiation-curable oligomer, for instance a urethane (meth)acrylate obtainable by reacting a polyol compound, a polyisocyanate compound, and a (meth)acrylate compound containing a hydroxyl group, and (B) dialkylaminobenzoate. The invention also provides a composition comprising radiation-curable oligomer (A) with (C) a hydroxyalkyl (meth)acrylate, and (D) at least one compound selected from the group consisting of 2,2-dimethoxy-1,2-diphenylethan-1-one, 2-hydroxy-2-methyl-1-phenylpropan-1-one, and 1-hydroxycyclohexyl phenyl ketone. The compositions of the present invention may be used as adhesives for optical disks.
摘要:
The extraction of a microbial or single cell oil, for example comprising one or more polyunsaturated fatty acids (PUFAs), directly from microbial cells is disclosed which avoids the need for solvents. After fermentation, the microbial cells are pasteurised, washed and the cell walls lysed or disrupted by a mechanical (e.g. homogenisation), physical (boiling or drying), chemical (solvents) or enzymatic (cell wall degrading enzymes) technique. The oil (containing the PUFA) is then separated from the resulting cell wall debris. This is achieved by centrifugation, which results is an oily phase (top layer) that contains the oil which that can be separated from an aqueous phase (containing the cell wall debris). The oil can then be extracted and if necessary the PUFA can be purified or isolated from the oil.
