Abstract

PURPOSE: To provide a coagulating agent excellent in safety and effect of coagulation by preparing cation-modified guar gum by introducing a specific amount of quaternary nitrogen-containing group into base material of guar gum.
CONSTITUTION: Guar gum is reacted with glycidyltrialkylammonium salt etc. in a solvent such as aqueous alcohol which includes alkali. Then, part of hydroxyl groups in the gum is substituted by quaternary nitrogen-contg. group represented by the formula I (R is a 1W3C alkyl gp., X⊖ is a monovalent anion) to form a cation-modified guar gum. At this time, it is necessary to provide 2wt% or more of such quaternary nitrogen-contg. group to the product. The obtained cation- modified guar gum coagulating agent is safe and exhibits excellent coagulation effect.
