Isingeniso

I-Ethyl 2-mercaptopropionate iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-ethyl 2-mercaptopropionate:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala.

- Iphunga: Iphunga elimnandi.

- I-Soluble: Incibilika emanzini nasezincibilikisini eziphilayo.

- I-Ethyl 2-mercaptopropionate iyi-asidi ebuthakathaka engakha ama-complexes ane-ion yensimbi.

 

Sebenzisa:

- Ingasetshenziswa futhi njenge-crosslinker yama-polymers okwenziwa kanye nerabha.

- I-Ethyl 2-mercaptopropionate ingasetshenziswa njengomthombo wesulfure ekulungiseleleni ama-selenides, ama-thioselenols nama-sulfide.

- Ingasetshenziswa futhi njenge-metal erosion inhibitor.

 

Indlela:

- I-Ethyl 2-mercaptopropionate ivame ukulungiswa ukusabela kwe-condensation ye-ethanol ne-mercaptopropionic acid, okubandakanya ukungezwa kwe-catalyst ye-acidic.

- Indlela yokusabela imi kanje: CH3CH2OH + HSCH2CH2COOH → CH3CH2OSCH2CH2COOH → CH3CH2OSCH2CH2COOCH3.

 

Ulwazi Lokuphepha:

- I-Ethyl 2-mercaptopropionate kufanele iphathwe ngokucophelela ukugwema ukuhogela, ukuthintana nesikhumba kanye nokuthintana namehlo.

- Gqoka izinto zokuzivikela ezifanele ezifana namagilavu, izibuko, nezingubo zokuzivikela lapho uzisebenzisa.

- Kufanele igcinwe futhi isetshenziswe endaweni engenawo umoya, kude nomlilo kanye nemithombo yokushisa.

- I-Ethyl 2-mercaptopropionate kufanele igcinwe kude nezingane nezilwane ezifuywayo futhi igcinwe kahle.
