Vinyl acetate (Ver) waa shey cooyin oo kiimikaad ah oo muhiim u ah qaaciddada molikalal ee c4h6o2, oo sidoo kale loo yaqaan vinyl acetate iyo vinyl acetate. Vinyl acetate waxaa inta badan loo isticmaalaa soosaarka aalkolada polyvinyl, ethylene-vinyl acyfymer (eva retate-vinyl chloride-vinyl chloride-vinyl chloride-vinyl chloride-vinyl chriolyer (cinjirka cagaha cad), fiber cad, abrylic iyo waxyaabaha kale ee acryl. Waxaa si weyn loogu isticmaalaa beeraha fiber-ka isku-darka, dahaarka, slurry, filim, ka baaraandeg maqaar, hagaajinta carrada, oo ay leedahay rajo balaadhan oo ah horumarinta iyo adeegsiga. Wadooyinka geeddi-socodka ee vinyl acetate waxaa ka mid ah 'Carbide Pastyne', Habka Gaaska Dabiiciga ee Acetylene iyo Habka Batroolka. Habka loo yaqaan 'acebidem' ee loo yaqaan 'acebidem' ayaa inta badan loo isticmaalaa Shiinaha, iyo awoodda wax soo saarka ee habka 'acebide acetyme' wuxuu gaari doonaa 62% sanadkii 2020.
Sanadihii la soo dhaafay, baahida suuqa ee Vinyl acetate ee Shiinaha ayaa muujisay isbeddel guud oo isbedel ah. Marka loo eego tirakoobka Ururka Arrimikada Kisthab ee Kist Chinate, sanadkii 2016, isticmaalka muuqaalka muuqaalka ee china wuxuu ahaa 1.34 milyan oo tan oo ah 2020, taas oo u horseedday hoos u dhac yar, taas oo horseeday in ay tahay 2.16 milyan oo tan ah. Deganaanshaha xaalada cudurka faafa qeybtii labaad ee sannadka iyo soo kabashada deg degga ah ee wax soo saarka dhaqaalaha, baahida loo qabo in si dhakhso ah looga soo kabsaday qeybtii labaad ee 2020, qiimaha suuqa ee 2021, iyo warshaduhu way soo kabsatay.
Qaab dhismeedka baahida ee Vinyl ee ka soo baxa Shiinaha waa mid xasilloon yahay, oo leh aalkolo polyvinyl, polyvinyl acetate, voevinyl acetate, vae reionyl iyo resin lont ah oo ah waxyaabaha ugu waaweyn. Sannadkii 2020, saamiga aalkolada polyvinyl ee qaab dhismeedka isticmaalka ee vinyl acetate ayaa gaari doona 65%, iyo isugeynta guud ee polyvinyl, oo ah loevinyl acetate, ponevinyl acetate, kareemka vae iyo lotion lont reins iyo eavin waxay noqon doonaan 31%.
Waqtigan xaadirka ah, Shiinaha ayaa leh awoodda ugu weyn ee Vinyl aduunka. Sanadkii 2020, awoodda Shiinaha ee Vinyl acetate ayaa gaari doonta 2.65 milyan oo tan, oo ay ku xisaabtamayaan qiyaastii 40% awoodda guud ee adduunka. Sanadihii la soo dhaafay, awoodda dambe ee ku taal warshadaha 'chinayl acetate' ayaa si tartiib tartiib ah ugala baxay, iyo awoodda horumarsan ayaa lagu daray si loo buuxiyo farqiga suuqa. Kordhinta joogtada ah ee qaab dhismeedka warshadaha, waxsoosaarka guud ee Shiinaha ayaa muujiyey isbeddelka kobaca guud. Sida ku xusan tirakoobka Ururka Arrim Worth-ka kiimikada ee Shiinaha, waxsoosaarka dusha sare ee ka soo saaray 1.91 milyan oo tan sanadkii 2016 ilaa 2.28 milyan oo tan sanadkii 2019, oo leh heerka kobaca sanadlaha ah ee xarunta 5.98%; Sanadkii 2020, qiimaha saliida ee caalamiga ah, waxsoosaarka batroolka Petrolem ee Dibedda ayaa la yareeyay, soo dejinta Vinyl acetate ee Shiinaha ayaa kordhay, iyo soosaarka gudaha ee ka soo baxa Vinyl acetate ayaa hoos u dhacay 1.99 milyan oo tan; Ilaa nuska labaad ee 2020, oo leh soo kabashada dhaqaalaha caalamiga ah iyo kor u kaca qiimaha saliida caalamiga ah, soo saarista warshadaha aqalka ee gudaha ee Vinyl ayaa diiriyay.
