    • PURPOSE: A novel manufacturing method of phenylmethyl cellulose is provided to be wisely used for the separation membrane of water treatment and the film for water treatment by using methyl cellulose to reduce the manufacturing time and the manufacturing cost, prevent environmental contamination due to by-product, and improve the manufacturing process. CONSTITUTION: A manufacturing method of phenylmethyl cellulose adds methyl cellulose of chemical formula 2, butyric acid and organic solvent of chemical formula 3 to the chemical formula 1 for obtaining the mixture by stirring it. (Step 1) The intended compound is dried to be obtained after the compound manufactured in the step 1 is primary washed with organic solvent and secondary washed with water. (Step 2) [Equation 1] (R is H or CH3 when the R is not H or CH3 at the same time in the chemical formula 2. R is H, CH_3 or C_6H_5CO in the chemical formula 1. The manufacturing method of phenylmethyl cellulose has the reaction ratio of methyl cellulose: butyric acid of step 1 to be 1: 1-2. Organic solvent of the step 1 is more than one selected from the group of pyridine, quinoline, furan, pyran and thiophene. The step 1 is performed at 100-130 °C.

    • PURPOSE: Provided is a submerged membrane system having improved mechanical properties such as strength and hydrophilicity, and excellent transmissivity and pollution-resistance. CONSTITUTION: The submerged membrane system is manufactured by coating a coating liquid comprising an organic/inorganic hybrid compound onto the surface of a tube-type macromolecular support. Particularly, the organic/inorganic hybrid compound is formed by the coordinate-linking of hydrophilic macromolecules and minerals selected from silica and titania in a ratio of 79-90 wt% to 10-30 wt%, and is contained in the coating liquid to a concentration of 2-6 wt%. The support is made of a macromolecular fiber woven with a yarn having a thickness of 200-500 denier to have an inside diameter of 0.5-3.0mm and an outside diameter of 1.0-4.0mm.
