Abstract: The present invention is related to a method of producing a peptide, characterized in contacting a reaction mixture with a base after a condensation reaction to hydrolyze while a basic condition is maintained until a ratio of a remaining unreacted active ester of an acid component is decreased to 1% or less in a liquid phase peptide synthesis method. According to the invention, a target peptide of high purity can be simply and efficiently produced by a continuous liquid phase synthesis method. Further, the present invention is related to a method of producing a peptide, characterized in using an amide-type solvent immiscible with water in a liquid phase peptide synthesis method. According to the invention, various peptides can be produced by the liquid phase synthesis method without being restricted by the amino acid sequence of the target peptide.

Abstract: The objective of the present invention is to provide a method for easily and efficiently producing cellulose beads which have pore shape suitable for an adsorbent and of which adsorption performance is excellent without using highly toxic and highly corrosive auxiliary raw material and without industrially disadvantageous cumbersome step. The method for producing porous cellulose beads according to the present invention is characterized in comprising (a) the step of preparing a fine cellulose dispersion by mixing a low temperature alkaline aqueous solution and cellulose, (b) the step of preparing a mixed liquid by adding a crosslinking agent to the fine cellulose dispersion, (c) the step of preparing an emulsion by dispersing the mixed liquid in a dispersion medium, (d) the step of contacting the emulsion with a coagulating solvent.
