Isingeniso
I-Methyl propionate, eyaziwa nangokuthi i-methoxyacetate. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-methyl propionate:
Ikhwalithi:
- Ukubukeka: I-Methyl propionate iwuketshezi olungenambala olusobala olunephunga elimnandi elikhethekile.
- Ukunyibilika: I-Methyl propionate inyibilika kakhulu kutshwala obungenamanzi nezincibilikizi ze-ether, kodwa ayincibiliki kancane emanzini.
Sebenzisa:
- Ukusetshenziswa kwezimboni: I-Methyl propionate iyi-solvent ebalulekile ye-organic esetshenziswa kakhulu kuma-coatings, ama-inki, ama-adhesives, okokuhlanza nezinye izimboni.
Indlela:
Ukulungiswa kwe-methyl propionate kuvame ukuqinisekiswa:
CH3OH + CH3COOH → CH3COOCH2CH3 + H2O
Phakathi kwazo, i-methanol ne-acetic acid isabela ngaphansi kwesenzo se-catalyst ukwakha i-methyl propionate.
Ulwazi Lokuphepha:
- I-Methyl propionate iwuketshezi oluvuthayo futhi kufanele igcinwe kude namalangabi avulekile namazinga okushisa aphezulu.
- Ukuchayeka ku-methyl propionate kungase kubangele ukucasuka kwamehlo nesikhumba, ngakho kufanele kuthathwe izinyathelo zokuphepha.
- Gwema ukuhogela umhwamuko we-methyl propionate futhi kufanele usebenze endaweni engenawo umoya.
- Uma ungenwa ngephutha noma uhogele umoya, funa usizo lwezempilo ngokushesha.
