Isingeniso

I-Methyl butyrate. Okulandelayo yisingeniso kwezinye izakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-methyl butyrate:

 

Ikhwalithi:

- I-Methyl butyrate iwuketshezi oluvuthayo olungancibiliki kalula emanzini.

- Inokuncibilika okuhle, kuncibilika otshwaleni, kuma-ether nakwezinye izinyibilikisi zemvelo.

 

Sebenzisa:

- I-Methyl butyrate ivame ukusetshenziswa njenge-solvent, i-plasticizer kanye ne-diluent kuma-coatings.

- Ingasetshenziswa futhi njengendawo ephakathi ku-organic synthesis yokulungiselela ezinye izinhlanganisela.

 

Indlela:

- I-Methyl butyrate ingalungiswa ngokuphendula i-butyric acid ne-methanol ngaphansi kwezimo ezine-acidic. I-reaction equation imi kanje:

CH3COOH + CH3OH → CH3COOCH2CH2CH3 + H2O

- Ukusabela kuvame ukuqhutshwa ngokushisa nge-catalyst (isb, i-sulfuric acid noma i-ammonium sulfate).

 

Ulwazi Lokuphepha:

- I-Methyl butyrate iwuketshezi oluvutha umlilo olungavutha lapho luvezwe amalangabi avulekile, amazinga okushisa aphezulu, noma ama-organic oxidant.

- Ukuthinta isikhumba namehlo kungase kubangele ukucasuka nokusha, kufanele kuthathwe izinyathelo zokuphepha.

- I-Methyl butyrate inobuthi obuthile, ngakho-ke kufanele igwenywe ukuze ihogele futhi ingene ngengozi, futhi isetshenziswe ngaphansi kwezimo ezinomoya omuhle.

- Kufanele kuqashelwe ukuvikela ukuthintana nama-oxidants, ama-asidi nama-alkali lapho kusetshenziswa noma kugcinwa.
