Intshayelelo
I-Ethyl 2-mercaptopropionate yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-ethyl 2-mercaptopropionate:
Umgangatho:
- Imbonakalo: Ulwelo olungenambala.
- Ivumba: Ivumba elibi.
-Inyibilikayo: Inyibilika emanzini nakwizinyibilikisi eziphilayo.
- I-Ethyl 2-mercaptopropionate i-asidi ebuthakathaka enokuthi yenze ii-complex kunye ne-ion zetsimbi.
Sebenzisa:
- Isenokusetyenziswa njenge-crosslinker yeepholima zokwenziwa kunye nerabha.
- I-Ethyl 2-mercaptopropionate ingasetyenziselwa njengomthombo wesulfure ekulungiseleleni i-selenides, i-thioselenols kunye ne-sulfides.
- Inokusetyenziswa kwakhona njenge-metal erosion inhibitor.
Indlela:
- I-Ethyl 2-mercaptopropionate idla ngokulungiswa yi-condensation reaction ye-ethanol kunye ne-mercaptopropionic acid, ebandakanya ukongezwa kwe-catalyst acidic.
- Ifomula yokusabela imi ngolu hlobo lulandelayo: CH3CH2OH + HSCH2CH2COOH → CH3CH2OSCH2CH2COOH → CH3CH2OSCH2CH2COOCH3.
Ulwazi ngoKhuseleko:
- I-Ethyl 2-mercaptopropionate kufuneka iphathwe ngokunyamekela ukuphepha ukuphefumla, ukudibanisa nolusu kunye nokudibanisa kwamehlo.
- Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglasi, kunye nempahla yokuzikhusela xa uzisebenzisa.
- Kufuneka igcinwe kwaye iqhutywe kwindawo engenamoya, kude nomlilo kunye nemithombo yobushushu.
- I-Ethyl 2-mercaptopropionate kufuneka igcinwe kude nabantwana kunye nezilwanyana zasekhaya kwaye zigcinwe ngokufanelekileyo.
