Liquid cationic etherifying agent is a kind of widely used fine chemical product.Lts chemical name is N-(3-chloro-2-hydroxypropyl)-three methylammonium chloride (abbreviated as CTA).Lts formula isC₆H₁₅NOCl₂,molecular weight is 188.1,and the structural formula is as follows:

    The product is a kind of 69% water solution at normal temperature.At basic conditions,it is immediately transformed into epoxy structure,and further reacts with such base materials as amylum and Guar gum to become cationic substances.Lts specific physical indexes are as the following:
    (1)Exterior:Colorless transparent liquid;
    (2)Active substance contect:≥69%;
    (3)1,3-dichloro propanol:≤10ppm;
    (4)Epoxy chloropropane:≤5ppm;
    (5)PH value:5-7(10%solution);
    (6)Solubleness:Easy to solve in water and 2-propanol.
Liquid cationic etherifying agent has the following characteristics:
    (1)The exterior of the product is transparent Liquid;it is colorless and tasteless,and has low impurity contect,less than 25ppm.
    (2)The product quality is stable because of adopting continuous production process.
    (3)The reactivity is high, up to 80%.
Liquid cationic etherifying agent as a cationic aid can be widely used in the following fields:
    (1)Paper industry
    It is mainly used as liquid cationic etherifying agent in large amounts to modify cellulose,cellulosederivatives and amylum.When reacted with amylum,cationic amylum can be produced,which can be used as internal gel painting adhesive,paper strengthening agent as well the aid for packing and fine fiber retention aid.
    (2)Textile industry
    Liquid cationic etherifying agentcan react with cotton fiber to improve the adhesion of the dyes.When reacted with amylum,cationic amylum can be produced,which can be used as twist yarn sizing agent.
    (3)Water treatment industry
    The suspended substances in water present negative charge,so cationic high molecules produced by Liquidcationic etherifying agent are widely used as flocculants for water purification.
    (4)Daily chemicals industry
    The cationic Guar gun,etc.,produced by the reaction of Guar gum and Liquid cationic etherifying agent,are important daily chemicals.
