Abstract

PURPOSE:To obtain the titled particle useful as a filler for liquid chromatography, by mixing cellulose xanthate with two kinds of water-soluble polymer compounds, coagulating and neutralizing the mixture and removing one of the polymer compounds from the obtained fine particles. CONSTITUTION:The objective porous fine particle is composed essentially of type-II cellulose and has the following characteristics. The crystallinity of the particle is 5-35% (determined by X-ray diffraction); the particle is composed of spherical or ellipsoidal particle having an average particle diameter of <=300mum; a differentiation curve of pore diameter and pore volume determined by mercury porosimetry has a peak of pore volume in the pore diameter range of 0.02-0.8mum; and the total pore volume in the above range is >=0.025ml/g. The particle can be produced e.g. by mixing cellulose xanthate with an alkaline aqueous solution of a 1st water-soluble polymer other than the xanthate and a 2nd water-soluble anionic polymer compound, coagulating the resultant dispersion of fine particles with an acid, neutralizing the product and removing the 1st polymeric compound from the obtained cellulose-containing fine particle.
