Acrylamide muaj cov pa roj carbon-carbon ob chav sib txuas thiab amide pawg, nrog rau ob chav sib txuas chemistry: nyob rau hauv ultraviolet irradiation lossis ntawm qhov kub ntawm qhov melting, yooj yim polymerization; Tsis tas li ntawd, ob chav sib txuas tuaj yeem ntxiv rau cov hydroxyl compound nyob rau hauv alkaline mob los tsim ib qho ether; Thaum ntxiv nrog thawj amine, monadic adder lossis binary adder tuaj yeem tsim tau. Thaum ntxiv nrog theem nrab amine, monadic adder tuaj yeem tsim tau. Thaum ntxiv nrog tertiary amine, quaternary ammonium ntsev tuaj yeem tsim tau. Nrog rau kev ntxiv ketone activated, qhov ntxiv tuaj yeem tam sim ntawd cyclized los tsim lactam. Kuj tseem tuaj yeem ntxiv nrog sodium sulfite, sodium bisulfite, hydrogen chloride, hydrogen bromide thiab lwm yam inorganic compounds; Cov khoom no kuj tuaj yeem copolymerize, xws li nrog lwm yam acrylates, styrene, halogenated ethylene copolymerization; Ob chav sib txuas kuj tuaj yeem txo los ntawm borohydride, nickel boride, carbonyl rhodium thiab lwm yam catalysts los tsim propanamide; Cov catalytic oxidation ntawm osmium tetroxide tuaj yeem tsim diol. Pawg amide ntawm cov khoom no muaj cov tshuaj zoo sib xws ntawm aliphatic amide: reacts nrog sulfuric acid los tsim ntsev; Nyob rau hauv lub xub ntiag ntawm alkaline catalyst, hydrolysis rau acrylic acid cag ion; Nyob rau hauv lub xub ntiag ntawm acid catalyst, hydrolysis rau acrylic acid; Nyob rau hauv lub xub ntiag ntawm dehydrating agent, dehydration rau acrylonitrile; React nrog formaldehyde los tsim N-hydroxymethylacrylamide.
siv
Acrylamide yog ib qho tseem ceeb thiab yooj yim tshaj plaws ntawm cov acrylamide series. Nws yog siv dav ua cov khoom siv raw rau cov organic synthesis thiab cov ntaub ntawv polymer. Cov polymer yaj tau hauv dej, yog li nws yog siv los tsim cov flocculant rau kev kho dej, tshwj xeeb tshaj yog rau kev flocculation ntawm cov protein thiab cov hmoov txhuv nplej siab hauv dej. Ntxiv rau flocculation, muaj cov thickening, shear resistance, txo qis resistance, dispersion thiab lwm yam zoo heev. Thaum siv ua cov khoom siv kho av, nws tuaj yeem ua rau cov dej permeability thiab noo noo ntawm cov av; Siv ua cov ntawv sau pabcuam, tuaj yeem ua rau lub zog ntawm daim ntawv, hloov cov hmoov txhuv nplej siab, ammonia resin soluble hauv dej; Siv ua cov tshuaj grouting, siv rau kev khawb av, kev khawb qhov av, kev khawb roj qhov dej, kev khawb av thiab pas dej engineering; Siv ua fiber modifier, tuaj yeem txhim kho cov khoom siv lub cev ntawm cov fiber hluavtaws; Siv ua cov tshuaj preservative, tuaj yeem siv rau cov khoom hauv av anticorrosion; Kuj tseem siv tau rau hauv cov khoom siv ntxiv rau kev lag luam zaub mov, pigment dispersant, luam ntawv thiab dyeing paste. Nrog phenolic resin kua, tuaj yeem ua rau cov iav fiber nplaum, thiab roj hmab ua ke tuaj yeem ua rau cov nplaum rhiab heev. Ntau yam khoom siv hluavtaws tuaj yeem npaj tau los ntawm kev sib xyaw 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, xim raw khoom.
