Soo-saare Qiimo Fiican Triphenylmethane saddex isocyanate (xalka ethyl acetate) CAS: 141-78-6 Summada: Desmodur_RE

1. Ethyl acetate waxaa loo isticmaalaa sidii dareere loogu talagalay varnishes, lacquers, iyo nitrocellulose; sida dhadhan miro aan macmal ahayn; nadiifinta dharka; iyo soo saarista xariir macmal ah iyo maqaar, cadar, iyo filimaan sawireed iyo saxanno (Merck 1996). Ethyl Acetate guud ahaan waxaa loo isticmaalaa sidii dareere falcelinta dabiiciga ah. Wasakhowga deegaanka; Wasakhowga cuntada.

2. Ethyl acetate waxaa loo isticmaalaa sida dareeraha iyo milan, waxaana loo door bidaa sababtoo ah qiimo jaban, sunta yar, iyo ur la aqbali karo. Tusaale ahaan, waxaa badanaa loo isticmaalaa in lagu nadiifiyo looxyada wareegga iyo qaar ka mid ah kuwa ka saara varnish-ka ciddiyaha (acetone iyo acetonitrile ayaa sidoo kale la isticmaalaa). Digirta qaxwada iyo caleenta shaaha waxaa lagu nadiifiyaa dareerahan. Waxaa sidoo kale loo isticmaalaa rinjiga sidii firfircooni ama adkeyn.[ciwaan loo baahan yahay] Ethyl acetate waxay ku jirtaa macmacaanka, cadarka, iyo miraha. Cadarka, si dhakhso ah ayuu u uumi baxaa, isagoo kaliya ka tagaya udgoonka cadarka maqaarka.
3 - 1 - Isticmaalka Shaybaarka
Shaybaarka dhexdiisa, isku-darka ay ku jiraan ethyl acetate ayaa si caadi ah loogu isticmaalaa koromatografiga tiirarka iyo soo saarista. Ethyl acetate si dhif ah ayaa loogu doortaa dareere falgal ah sababtoo ah waxay u nugul tahay hydrolysis iyo trans esterification.
3 - 2 - Ka dhaca khamriga
Ethyl acetate waa ester-ka ugu badan ee khamriga ku jira, waana natiijada ka dhalata asiidhka dabiiciga ah ee ugu badan ee isbeddela - acetic acid, iyo khamriga ethyl ee la soo saaro inta lagu jiro halsano. Carafka ethyl acetate wuxuu aad ugu muuqdaa khamriga yar yar wuxuuna gacan ka geystaa aragtida guud ee "miro-dhalashada" ee khamriga.
3 - 3 - Wakiilka dilka unugyada
Dhinaca cilmiga entomology-ga, ethyl acetate waa daawo neefsasho oo waxtar leh oo loo isticmaalo ururinta cayayaanka iyo daraasadda. Weel wax lagu dilo oo lagu shubay ethyl acetate, uumiga ayaa si dhakhso ah u dili doona cayayaanka la ururiyay (badanaa dadka waaweyn) iyada oo aan la burburin. Maadaama uusan ahayn mid hygroscopic ah, ethyl acetate sidoo kale waxay cayayaanka ka dhigtaa mid jilicsan si ay ugu oggolaato rakibid habboon oo ku habboon ururinta.

3. Kaalmo dawo (dhadhan); waxyaabaha ku jira miro macmal ah; dareere loogu talagalay nitrocellulose, varnishes, lacquers, iyo daawada diyaaradda; soo saarista budada aan qiiqa lahayn, maqaar macmal ah, filimada iyo saxannada sawir qaadista, xariir macmal ah, cadar; dharka nadiifinta, iwm.
