Ethyl 3-Mercaptopropionate (CAS#5466-6-8) Chiyambi

Zathupi:
Maonekedwe: Nthawi zambiri zamadzimadzi zowoneka bwino zachikasu zokhala ndi fungo lapadera.
Malo Owira: Nthawi zambiri pa 190 - 192 ° C (pakuthamanga kwa mumlengalenga), kuchuluka kwa malo otentha kumatha kusiyana pang'ono kutengera miyeso ndi chiyero.
Kachulukidwe: Kuchulukana kwachibale ndi pafupifupi 1.07 (madzi = 1), zomwe zikutanthauza kuti ndizolemera pang'ono kuposa madzi ndipo panthawi yosungira ndikugwiritsa ntchito, zimakhala pansi ngati zitasakanizidwa ndi madzi.
Kusungunuka: Kusungunuka pang'ono m'madzi, koma kusakanikirana ndi zosungunulira zambiri za organic monga ethanol, etha, acetone, ndi zina zotero, zomwe zimapangitsa kuti azikhudzidwa kwambiri ndi machitidwe osiyanasiyana osungunulira m'machitidwe a organic synthesis.
Chemical katundu:
Kugwiranso ntchito kwa gulu: Gulu la sulfhydryl (-SH) mu molekyulu limakhala ndi reactivity yamphamvu ndipo ndi malo omwe amachitirapo zinthu zambiri. Imatha kukhala ndi condensation reaction ndi mankhwala a carbonyl monga aldehydes ndi ketoni kuti apange mankhwala a thioether; Itha kusinthidwanso ndi ma halogenated hydrocarbons kuti ipange zomangira zatsopano za kaboni-sulfure, zomwe zitha kugwiritsidwa ntchito popanga mamolekyu ovuta.
Kukhazikika: Imakhala yokhazikika kutentha ndi kupanikizika, koma pansi pa kuwala, kutentha kwakukulu kapena kukhalapo kwa okosijeni amphamvu, magulu a sulfhydryl akhoza kukhala oxidized, zomwe zimapangitsa kusintha kwa mankhwala a mankhwala, kotero iwo ayenera ziyenera kusungidwa ndi kugwiritsidwa ntchito pamikhalidwe yoyenera, ndipo nthawi zambiri zimalimbikitsidwa kusungidwa pamalo ozizira, mpweya wabwino komanso wamdima, ndikupewa kukhudzana ndi ma okosijeni amphamvu.
Njira Yophatikizira:
Nthawi zambiri amakonzedwa ndi esterification ya 3-mercaptopropionic acid ndi Mowa pamaso pa chothandizira acidic monga sulfuric acid. Pazimenezi, choyamba, gulu la carboxyl ndi gulu la hydroxyl la ethanol limakhala ndi nucleophilic substitution reaction pansi pazikhalidwe za acidic kupanga ma ester bond, ndipo nthawi yomweyo madzi amapangidwa. Pamapeto pa zomwe zimachitika, mankhwalawa amayenera kuyeretsedwa kudzera muzitsulo zotsatizana pambuyo pake monga neutralization, kutsuka madzi, ndi distillation kuti apeze Ethyl 3-Mercaptopropionate yapamwamba kwambiri.
Gwiritsani ntchito:
Munda wa fungo: Umakhala ndi fungo lapadera ndipo umagwiritsidwa ntchito ngati fungo lapakati pakupanga fungo lonunkhira, lomwe limatha kuwonjezera kununkhira kwapadera komanso kusanjikiza kwamafuta osakanikirana, ndipo nthawi zambiri amagwiritsidwa ntchito kuphatikiza zokometsera monga zipatso ndi nyama kuti zikwaniritse zosowa. za zakudya, zodzoladzola ndi mafakitale ena onunkhira osiyanasiyana.
Pharmaceutical field: Itha kugwiritsidwa ntchito ngati zopangira kapena zapakatikati pakupanga mankhwala kupanga ma cell omwe ali ndi zochitika zenizeni zamoyo. Mwachitsanzo, pakuphatikizika kwa mankhwala okhala ndi sulfure, magulu awo a sulfhydryl amatha kulowetsedwa mu molekyulu yomwe akufuna kudzera muzochita zamankhwala, potero akupereka zochitika zapadera zamankhwala pamankhwala, monga antioxidant, antimicrobial, kapena regulating enzyme.
Agriculture: Ilinso ndi ntchito inayake pakuphatikizika kwa mankhwala ophera tizilombo, posintha mawonekedwe ake a maselo ndikuyambitsa magulu omwe akugwira ntchito, kuti athe kuwonetsa zotsatira zabwino zowononga tizirombo kapena tizilombo toyambitsa matenda pa mbewu, zomwe zimathandiza kukonza zokolola ndi mtundu wa mbewu. ndikuwonetsetsa kukhazikika kwa zokolola zaulimi.
