Acrylamidemuaj carbon-carbon ob daim ntawv cog lus thiab amide pawg, uas muaj cov tshuaj lom neeg ntawm ob daim ntawv cog lus: nws yog ib qho yooj yim rau polymerize nyob rau hauv ultraviolet irradiation los yog melting point kub; Tsis tas li ntawd, ob daim ntawv cog lus yuav muab ntxiv rau hydroxyl tebchaw nyob rau hauv alkaline tej yam kev mob los tsim ethers. . Thaum ntxiv nrog thawj amine, unary lossis binary admixture tuaj yeem tsim tawm. Thaum ntxiv nrog rau lwm yam amine, tsuas yog unary admixture tuaj yeem tsim tau. Thaum ntxiv nrog tertiary amine, quaternary ammonium ntsev tuaj yeem tsim tau. Nrog rau qhov sib ntxiv ntawm activated ketone, lub admixture tuaj yeem raug cyclized tam sim ntawd los tsim lactam.Nws tseem tuaj yeem ntxiv nrog sodium sulfite, sodium bisulfite, hydrogen chloride, hydrogen bromide thiab lwm yam inorganic compounds; Cov khoom no tuaj yeem ua tau copolymerized, xws li nrog lwm cov acrylates, styrene, vinyl halide copolymerization; Ob daim ntawv cog lus tseem tuaj yeem raug txo los ntawm borohydride, nickel boride, carbonyl rhodium thiab lwm yam catalysts los tsim propionamide. Diol tuaj yeem tsim los ntawm catalytic oxidation nrog osmium tetroxide.Cov amide pawg ntawm cov khoom no muaj cov tshuaj lom neeg ntawm aliphatic amide: hnov mob nrog sulfuric acid los ua ntsev; Nyob rau hauv lub xub ntiag ntawm alkaline catalyst, acrylic ions tau hydrolyzed rau daim ntawv. Nyob rau hauv lub xub ntiag ntawm acid catalyst, acrylic acid yog hydrolyzed. Nyob rau hauv lub xub ntiag ntawm dehydrating tus neeg sawv cev, acrylonitrile yog dehydrated. Nws reacts nrog formaldehyde los ua N-hydroxymethylacrylamide.
Acrylamideyog ib qho tseem ceeb tshaj plaws thiab yooj yim tshaj plaws acrylamide systems. Nws yog dav siv los ua raw khoom rau cov organic synthesis thiab cov ntaub ntawv polymer.The polymer yog soluble hauv dej, yog li nws yog siv los tsimflocculanthauv kev kho dej, tshwj xeeb tshaj yog rau flocculation ntawm cov protein, hmoov txhuv nplej siab hauv dej muaj txiaj ntsig zoo. Ntxiv nrog rau flocculation, muaj thickening, shear resistance, tsis kam, dispersion thiab lwm yam khoom zoo heev.Thaum siv los ua cov av txias, nws tuaj yeem ua kom cov dej permeability thiab noo noo khaws cov av.;Siv raws li daim ntawv muab tub lim ntxiv, tuaj yeem ua kom muaj zog ntawm daim ntawv, nyob rau hauv qhov chaw ntawm cov hmoov txhuv nplej siab, dej soluble ammonia resin; Siv los ua cov tshuaj grouting tus neeg sawv cev, siv nyob rau hauv civil engineering qhov excavation, roj zoo drilling, mine thiab dam engineering plugging; Siv los ua fiber ntau modifier, tuaj yeem txhim kho lub cev khoom ntawm hluavtaws fiber ntau; Siv los ua ib qho tshuaj tiv thaiv, tuaj yeem siv rau cov khoom siv hauv av anticorrosion; Kuj tseem siv tau rau hauv kev lag luam khoom noj khoom haus additives, pigment dispersant, luam ntawv thiab dyeing muab tshuaj txhuam.Nrog phenolic resin tov, tuaj yeem ua rau iav fiber ntau nplaum, thiab roj hmab ua ke tuaj yeem ua rau siab rhiab nplaum. Ntau yam khoom siv hluavtaws tuaj yeem npaj los ntawm polymerization nrog Vinyl acetate, styrene, vinyl chloride, acrylonitrile thiab lwm yam monomers. Cov khoom no kuj tseem siv tau ua tshuaj, tshuaj tua kab, zas xim, pleev xim rau cov ntaub ntawv raw.
