Isingeniso

I-Methyl 3-(methylthio)propionate. Inezici ezilandelayo:

 

1. Ukubukeka: I-Methyl 3-(methylthio)propionate iwuketshezi olungenambala olunephunga elikhethekile lesulfure.

 

2. Ukunyibilika: Kungancibilika kuzincibilikisi eziningi eziphilayo, njengotshwala, ama-ether nama-hydrocarbon anephunga elimnandi.

 

3. Ukuzinza: Azinzile uma kuqhathaniswa nezinga lokushisa legumbi, kodwa kancane kancane izobola ngaphansi kwezinga lokushisa eliphezulu nokukhanya.

 

Ukusetshenziswa okuyinhloko kwe-methyl 3-(methylthiopropionate) kufaka:

 

1. I-Chemical reagent: Ivamise ukusetshenziswa njenge-reagent noma i-intermediate ku-organic synthesis, futhi ingabamba iqhaza esterification, etherification, ukunciphisa nokunye ukusabela.

 

2. Izinongo nama-flavour: Inephunga elikhethekile lesibabule futhi ingasetshenziswa ukulungisa iphunga elikhethekile kumakha, insipho neminye imikhiqizo.

 

3. Izibulala-zinambuzane: I-Methyl 3-(methylthio)propionate ingasetshenziswa ukulungisa izingxenye ezithile zezibulala-zinambuzane ukuze zidlale indima yokubulala izinambuzane noma yokulondoloza.

 

Izindlela eziyinhloko zokulungiselela i-methyl 3-(methylthio)propionate yilezi:

 

I-Methyl mercaptan (CH3SH) ne-methyl chloroacetate (CH3COOCH2Cl) zisabela ngaphansi kwe-catalysis ye-alkali.

 

Ulwazi lokuphepha: I-Methyl 3-(methylthio)propionate izothobela lezi zinyathelo zokuphepha ezilandelayo:

 

1. Gwema ukuhogela umoya noma ukuthinta isikhumba, futhi gqoka izinto zokuzivikela ezifanele lapho usebenzisa.

 

2. Gwema ukuthintana nama-oxidizing agents aqinile ukuze ugweme ukusabela okuyingozi.

 

3. Gcina endaweni epholile, engenamoya, kude nomlilo nokushisa.

 

4. Uma uhogela umoya ngephutha noma uthintwa, geza indawo ethintekile ngokushesha futhi ufune usizo lwezokwelapha.

 

5. Uma usebenzisa noma uphatha inhlanganisela, izinqubo ezifanele zokusebenza zokuphepha kufanele zilandelwe ngokuqinile.
