Neopentyl Glycol (NPG) (CAS: 126-30-7) waxaa inta badan loo isticmaalaa soo saarida resins, balaastikada iyo qaar ka mid ah surfactants.Neopentyl Glycol wuxuu leeyahay hawlo badan oo kala duwan, kuwaas oo doorka ugu weyni yahay in la soo saaro qaboojinta saliidda, resin alkyd, resin polyester unsaturated, xumbo jilicsan oo jilicsan oo poliurethane ah, qalab dahaaran, khad daabacan, balaastikada synthetic, wakiilka dufanka duulista iyo qaar ka mid ah wakiilka surfactant. lagu daro saliidaha heerka sare ah iyo kiimikooyinka kale ee wanaagsan.Neopentyl Glycol waa dareere aad u fiican waxaana loo isticmaali karaa kala-soocidda hydrocarbons udugga iyo cycloalkyl hydrocarbons.Neopentyl Glycol wuxuu leeyahay iska caabin biyaha, caabbinta kiimikaad, iyo iska caabinta cimilada.Daboolkeeda dubista amino waxay leedahay xajin dhalaaleed oo wanaagsan mana isu rogo huruud.Waxa kale oo loo isticmaali karaa walxo cayriin ah oo loogu talagalay soo saarista xakamaynta polymerization, xasiliyeyaasha iyo sunta cayayaanka.BalaastiisteIsku-dhafka dabiiciga ah.Polyester wax cayriin synthetic.Loo isticmaalo sida dareere wanaagsan, sidoo kale balaastikada iyo isku-dhafka kiimikada.NPG waxay leedahay iska caabin wanaagsan oo hydrolytic sidoo kale iska caabin u ah kiimikooyinka kala duwan marka loo isticmaalo soo saarista rinjiga.Qalabka daawada, sunta cayayaanka, walaxda xabagta.Waa aalkolo gaar ah oo bixisa faa'iidooyin waxqabad sare leh codsiyo badan oo isticmaalka dhamaadka ah sababtoo ah xasilloonida kimikalka iyo kimikalka sare.Waa diol gaar ah oo bixiya faa'iidooyinka waxqabadka sare ee codsiyada badan ee isticmaalka dhamaadka.Faa'iidooyinkan waxaa laga soo qaatay qaab dhismeedka kiimikada.Meesha ay ku yaalaan kooxaha hydroxyl ee atamka kaarboonka aasaasiga ah waxay u oggolaaneysaa in si degdeg ah loo nadiifiyo.Intaa waxaa dheer, labada kooxood ee methyl, halkii ay ka ahaan lahaayeen labada atamka hydrogen ee caadiga ah, alfa carbon atom ayaa mas'uul ka ah xasiloonida kiimikada iyo kuleylka sare ee Neopentylglycol iyo ka soosaarkeeda.
