Isingeniso

I-2,3,4,5-Tetramethyl-2-cyclopentenone (eyaziwa nangokuthi i-dicyclohexanone) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, indlela yokukhiqiza kanye nolwazi lokuphepha:

Ikhwalithi:

- Ukubukeka: 2,3,4,5-tetramethyl-2-cyclopentenone uketshezi olungenambala.

- Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo njengama-ether notshwala.

Sebenzisa:

- I-Chemical synthesis: I-2,3,4,5-tetramethyl-2-cyclopentenone iyingxenye ebalulekile ekuhlanganiseni kwe-organic.

- Izinongo: Inephunga elimnandi elifana nelikalamula futhi lisetshenziswa kakhulu embonini yezinongo.

Indlela:

I-2,3,4,5-Tetramethyl-2-cyclopentenone ivame ukulungiswa yi:

- I-Oxidation ye-isooctanol: I-Isooctanol isabela nge-oxygen ukuze ikhiqize i-2,3,4,5-tetramethyl-2-cyclopentenone ngokusebenzisa isenzo se-catalyst.

Ulwazi Lokuphepha:

- I-2,3,4,5-Tetramethyl-2-cyclopentenone ingase ithukuthele kancane ekuhlanzekeni okuphezulu.

- Ngenxa yokuthi iyi-solvent ephilayo, kufanele kuqashelwe ukuvimbela ukuhogela, ukuthintana nesikhumba namehlo lapho uyisebenzisa, kanye nokuqinisekisa ukuthi isetshenziswa endaweni enomoya omuhle.

- Gcina endaweni epholile, eyomile ekude nomlilo kanye nama-oxidants.

Okwedlule: 2 2-diethoxyacetaldehyde (CAS# 5344-23-0)

Olandelayo: I-N-Boc-N'-(2-chlorobenzyloxycarbonyl)-L-lysine(CAS# 54613-99-9)
