Abstract
A particulate body having a hollow particle and a surface polymer disposed on the outside of the hollow particle and suitable for use in solid phase synthesis, especially production of peptides and oligonucleotides. The particulate body may be used as a chromatography stationary phase column and the buoyancy of the body allows the column to be packed efficiently from the bottom reducing the risk of damage to the stationary phase. The buoyancy of the particulate body may also allow species for example a catalyst to be suspended in a liquid phase to allow reactions, for example hydrolysis of vegetable oil and esterification to produce biodiesel to be carried out with a reduced risk of catalyst loss from a reaction zone.
Claims33
A particulate body comprising a hollow particle comprising a polymer and, optionally a surface polymer disposed on the outside of the hollow particle.
(canceled)
A method for producing a particulate body material comprising the steps of providing a hollow particle contacting the particle with a monomer or solution of a monomer, effecting polymerisation of the monomer so as to form a surface polymer coating on the hollow particle(s).
-29. (canceled)
A method for the production of a fatty acid comprising contacting a vegetable oil with a buoyant, hollow particulate body having an enzyme capable of hydrolyzing the vegetable oil bound to the body in a reaction zone to produce fatty acid and glycerol, withdrawing glycerol from the reaction zone leaving the enzyme in the reaction zone.
The process any one of claims 32 to 311 claim 32 wherein the surface polymer is selected from polydimethylacrylamide, polyethyelene glycol and polystyrene.
