Fasalka Warshadaha Kiimikooyinka Aasaasiga ah ee Dabiiciga ah Ethyl Acetate

Macluumaadka Alaabta

Ethyl Acetate waa hal nooc oo ka mid ah Ester Compounds, formula kiimikaad waa C4H8O2, waa nooc ka mid ah ester leh kooxda functional-COOR (double bond u dhexeeya carbon iyo ogsijiin), waxa ay ku dhici kartaa alkoholyssis, ammonia, kala beddelashada ester, hoos u dhac iyo falcelinta kale ee caadiga ah ee esters guud, waxaa inta badan loo isticmaalaa sida dareere ah, nadiifinta iyo udgoon la cuni karo.

Sifooyinka Kiimikada ee Ethyl Acetate
Ethyl acetate waxay ku dhici kartaa khamriga, ammonolysis, ester sarrifka, hoos u dhigista iyo falcelinta kale ee caadiga ah ee esters guud. Is-condensation ee joogitaanka birta sodium si loo soo saaro 3-hydroxy-2-butanone ama ethyl acetoacetate; iyo falcelinta reagent Grignard si ay u soo saarto ketone, falcelin dheeraad ah si aad u hesho aalkolo jaamacadeed. Ethyl acetate aad bay u deggan tahay kulaylka waxayna ahaanaysaa mid aan isbeddelin marka lagu kululeeyo 290 ° C 8 ilaa 10 saacadood. Waxay u jajabisaa ethylene iyo acetic acid marka ay dhex maraan birta kulul ee casaanka ah, hydrogen, carbon monoxide, carbon dioxide, acetone iyo ethylene by budada zinc kuleylinta 300 ~ 350 ℃, iyo biyo, ethylene, carbon dioxide iyo acetone by fuuqbaxa aluminium oxide at 360 ℃. Ethyl acetate waxaa ka soo baxa shucaaca ultraviolet si ay u soo saarto 55% carbon monoxide, 14% carbon dioxide iyo 31% hydrogen ama methane iyo gaasas kale oo guban kara. Falcelinta ozone waxay soo saartaa acetaldehyde iyo acetic acid. Halides hydrogen gaseous waxay la falgalaan ethyl acetate si ay u sameeyaan ethyl halide iyo acetic acid. Hydrogen iodide waa ka falcelinta ugu badan, halka hydrogen chloride uu u baahan yahay cadaadis si uu u dumiyo heerkulka qolka, waxaana lagu kululeeyaa 150 ° C leh fosfooraska pentachloride si ay u sameeyaan chloroethane iyo acetyl chloride. Ethyl acetate waxay samaysaa dhismooyin crystalline oo kala duwan oo leh cusbo bir ah. Dhismayaashani waxay ku milmeen ethanol anhydrous laakiin kuma milmayaan ethyl acetate oo si fudud ayaa biyo loogu shubaa.

Macluumaadka shirkadda

Waxyaalaha ay shirkadu soo dejiso iyo wax-soo-saarka dhoofinta ugu badan waxaa ka mid ah

(1) Alaabta caagga ah : Marka alaabta caagga ah la qaabeeyo, ka dib marka lagu cadaadiyo cadaadiska sare, isku-duubnaanta elastomer lama tirtiri karo, taas oo inta badan soo saarta hoos u dhac aan xasilloonayn marka badeecada laga soo saaro caaryada (heerka yaraynta caaggu wuu kala duwan yahay iyadoo ku xiran nooca caag), kaas oo kaliya la fududeyn karo ka dib waqti cayiman. Sidaa darteed, marka naqshadaynta alaabta caag ah ee bilawga, iyada oo aan loo eegin caanaha ama caaryada, waxay u baahan yihiin in si taxadar leh loo xisaabiyo si ay u dhigmaan, haddii kale, way sahlan tahay in la soo saaro cabbirka alaabta aan degganeyn, taasoo keentay tayada alaabta hooseysa.

(2) Dhexdhexaadin : Iskudhis kiimikaad ah oo laga soo saaray iskudhisyo fudud oo caadi ahaan loogu talagalay in loo isticmaalo isku-dhafka dambe ee alaabooyinka kakan . Nooc kiimiko ah oo cimri gaaban ayaa caadiyan ku samaysma fal-celin ahaan tallaabo dhexdhexaad ah oo u dhaxaysa walxaha bilawga ah iyo badeecada u dambaysa .
