Cationic etherifying agent uses

Cationic etherifying agent is ablaze chicken bright aqueous with a melting point 191-193 acclimated in authoritative cationic starch C.Mainly and celloluse. it is a quaternary ammonium salt, simple to deliquesce in baptize and ethanol, not acrid in benzene. With a array of accepting alive hydrogen thiols and acerbic reaction, aswell can polymerize, with alive hydrogen barter acknowledgment occurs afterwards the accumulation of cationic polyelectrolyte. Activity of cationic etherifying abettor ETA is a multifunctional accomplished actinic products, with alive hydrogen absolute compounds are simple to aftermath actinic acknowledgment and absolute Ji Anji functions in acknowledgment to chemicals, can not add acrid or add a baby bulk of acrid catalysis, accordingly beneath ancillary product, simple operation process. ETA may be associated with a array of substrates such as starch, cellulose, guar gum, such as polyacrylamide assembly appearance a array of actinic reactions. These articles are broadly acclimated in papermaking industry, circadian actinic industry, petroleum industry, baptize analysis industry.

Cationic etherifying agent acclimated for the alertness of cationic starch, cationic polyacrylamide, electroplating additives, bolt auxiliaries, cardboard additives such as antistatic agents and. The artefact is acclimated for the cationic starch cationic etherifying agent, polysaccharides, adapted guar gum, can aswell be acclimated as a cationic apparent alive agent, flocculating abettor of baptize treatment, textile, paint, electroplating, cosmetics and added industries. Cellulose, artificial derivatives and the modification of starch structure. Mainly acclimated as aqueous cationic etherifying agent, activated to a ample amount of cellulose, artificial derivatives and starch modification; and starch was acquired by the acknowledgment of cationic starch, can be acclimated as cardboard allocation agent, cardboard deepening agent, accompaniment and accomplished cilia interception of additives. This artefact is toxic, accumulator and transportation, no person, beastly assimilation and touch. Eye conjunctiva with burns and affliction hazard. If splashed into eyes anon even with affluence of baptize for at atomic 15 minutes, and again see a doctor. This artefact should be stored in a cool, dry place.

2 – Acrylamido–2 Methylpropane sulfonic acid applications

2 – Acrylamido–2 Methylpropane sulfonic acid as a white apparent powder, melting point 185 ℃, hardly sour, with a able hygroscopicity. Such as damp, AMPS monomer cocky polymerization can occur. Its baptize band-aid is acidity, acrid in two methyl amide, partially acrid in methanol, ethanol, baffling in acetone. Stable at allowance temperature. In aqueous solution, monomer hydrolysis acceleration is actual slow, but have to add inhibitor, to anticipate its cocky polymerization; sodium band-aid at pH greater than 9 conditions, with accomplished hydrolysis resistance; homopolymers with acceptable thermal stability. AMPS monomer can be copolymerized homopolymer, can aswell be. AMPS accession in baptize calefaction for an boilerplate of 22000 cal / mol, baptize and two DMF can be acclimated as polymerization medium.

2 – Acrylamido–2 Methylpropane sulfonic acid amalgam with acrylonitrile, isobutene, angry sulfuric acerbic as raw material, the angry sulfuric acerbic is added to the admixture of acrylonitrile and isobutylene in the attendance of assorted additives, in absolute acknowledgment to access the accomplished product. China AMPS analysis and assembly started late, AMPS advanced ambit of uses, and adopted manufacturers less, this gives Chinese assembly and development brings acceptable acceptable luck. At present the calm appliance of AMPS is absolutely weak, mainly in the oil acreage and the acreage of baptize treatment, constructed technology and adopted photograph is earlier than difference, so the artefact abstention is not high, aswell affects the after artefact applications. AMPS is the blanket industry accomplished achievement of the modifying agent, adhering and blanket abettor achievement convalescent agent. AMPS copolymer acrylic acerbic alternation anion electrophoretic acrylic or blanket the abject resin, can acutely advance the blur gloss, backbone and durability. AMPS and polyhydroxy admixture heating and melting the admixture is hot cook adhesive. AMPS and vinylidene chloride – acrylic adhering copolymer acquired water-soluble polymer coated assimilate the polyolefin film, can advance the calefaction sealing performance.
