Isingeniso

I-6-Heptyltetrahydro-2H-pyrano-2-one, eyaziwa nangokuthi i-caprolactone, i-γ-caprolactone, iyinhlanganisela yezinto eziphilayo.

 

Ikhwalithi:

I-6-Heptyltetrahydro-2H-pyran-2-one iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile. Inephunga elikhethekile elifana namanzi nezindawo ezincibilikayo emanzini, otshwaleni, nama-ether. Kuyi-solvent engeyona i-polar engahlangani kalula nezincibilikisi eziningi ezivamile zemvelo.

 

Sebenzisa:

I-6-Heptyltetrahydro-2H-pyrano-2-one iyi-solvent evame ukusetshenziswa esetshenziswa kabanzi ku-organic synthesis kanye nemboni yemithi. Ivamise ukusetshenziselwa ukuncibilikisa izinto ezifana ne-cellulose, ama-fatty acids, ama-resin emvelo kanye nama-synthetic, isitashi, njll. Ingasetshenziswa futhi njengesixazululi sezinto zokumboza, oyinki, izinto zokunamathisela, nezithasiselo zenjoloba.

 

Indlela:

Indlela yokulungiselela ye-6-heptyltetrahydro-2H-pyran-2-one itholakala ngokuyinhloko ngokusabela kwe-cyclohexanone ne-sodium hydride ku-solvent yotshwala. Indlela eqondile yokulungiselela ukushisa nokusabela i-cyclohexanone nge-sodium hydride kusincibilikisi sotshwala njenge-ethylene glycol noma i-isopropanol ukukhiqiza i-6-cyclohexyl-2H-pyrano-2-one, bese uthola umkhiqizo ohlosiwe ngokusabela kwe-oxidation ye-cyclohexyl i-heptyl.

 

Ulwazi Lokuphepha:

I-6-Heptyltetrahydro-2H-pyrano-2-one inobuthi obuphansi, kodwa kusabalulekile ukunaka ukusetshenziswa kwayo okuphephile. Kuwuketshezi oluvuthayo futhi kufanele kugwenywe ukuthintana namalangabi avulekile kanye namazinga okushisa aphezulu. Ukuphefumula kwama-vapors kufanele kugwenywe ngesikhathi sokusebenza, ukusebenza kufanele kwenziwe endaweni enomoya omuhle, futhi kufanele kuthathwe izinyathelo zokuzivikela ezifanele, njengokugqoka izibuko zokuzivikela namagilavu.
