ethyl 9-oxodec-2-enoate (CAS#57221-88-2)
ethyl 9-oxodec-2-enoate (CAS#57221-88-2) Gabatarwa
Na zahiri:
Bayyanar: Yawancin lokaci mara launi zuwa ruwan rawaya mai haske tare da wari na musamman.
Tushen tafasa: Gabaɗaya a kusa da [ƙayyadaddun ƙimar ƙimar tafasa] ° C (a daidaitaccen yanayin yanayin yanayi), halayen ma'aunin tafasar sa yana ƙayyade yanayin zafin jiki a cikin rabuwa da ayyukan tsarkakewa kamar distillation, wanda yana da mahimmanci don raba fili daga cakuda amsa. .
Density: Ƙwararren dangi yana game da [ƙayyadadden ƙimar ƙima] (ruwa = 1), wanda ke taimakawa wajen ƙayyade ƙaddamarwa lokacin da aka haɗe shi da wasu abubuwa da yanayin rarrabawa a cikin tsarin amsawa yayin ajiya da amfani.
Solubility: Yana da kyau solubility a cikin na kowa Organic kaushi kamar ethanol, ether, chloroform, da dai sauransu, kuma zai iya zama miscible tare da wadannan kwayoyin kaushi, wanda shi ne dace domin shiga daban-daban halayen kamar yadda reactants ko intermediates a Organic kira halayen, yayin da solubility. a cikin ruwa ne in mun gwada da matalauta.
Abubuwan sinadarai:
Reactivity na rukuni na aiki: Kwayar ta ƙunshi ƙungiyoyin ester da alkene bonds, ƙungiyoyin aiki masu mahimmanci guda biyu, waɗanda ke sa ya wadatar da sake kunna sinadarai. Ƙungiyoyin Ester na iya fuskantar halayen hydrolysis don samar da barasa masu dacewa da acid a ƙarƙashin yanayin acidic ko alkaline, kuma ana amfani da wannan amsa sau da yawa a cikin fassarar rukuni na aiki da gyare-gyaren fili a cikin haɗin gwiwar kwayoyin halitta. Haɗin Olefin na iya shiga cikin ƙarin halayen, kamar halayen hydrogenation tare da hydrogen don cika shaidu biyu; Hakanan yana iya jurewa halayen ƙari na electrophilic tare da halogens, hydrogen halides, da dai sauransu, don gabatar da sabbin ƙungiyoyin aiki da gina ƙarin hadaddun tsarin kwayoyin halitta don haɓakar mahadi tare da takamaiman ayyuka.
Kwanciyar hankali: Yana da ingantacciyar karko a yanayin zafin jiki da matsa lamba, amma tsarinsa na ƙwayoyin cuta na iya canzawa a ƙarƙashin yanayi kamar haske, zafin jiki mai ƙarfi, oxidant mai ƙarfi ko ƙarfi acid da alkali. Misali, igiyoyin alkene na iya fuskantar sauye-sauyen radicals a ƙarƙashin haske ko yanayin zafi mai girma, wanda ke haifar da ƙaura ko oxidation na shaidu biyu; Ƙungiyar ester tana haɓaka halayen hydrolysis a ƙarƙashin yanayi mai ƙarfi na acid-base, wanda ke canza kaddarorin sinadarai da reactivity na fili. Don haka, wajibi ne a kula don guje wa haɗuwa da waɗannan yanayi mara kyau yayin ajiya da amfani, kuma gabaɗaya ya dace da ajiya a cikin yanayi mai sanyi, bushe, duhu da nisa daga ƙaƙƙarfan oxidants da acid da alkalis.
