Intshayelelo
I-Isopentenyl thiol yi-organic compound. Iimpawu zayo zezi zilandelayo:
1. Imbonakalo: I-Prenyl mercaptans ayinambala okanye lulwelo olutyheli kunye nevumba elikhethekileyo le-thienol.
2. Ukunyibilika: I-Isopentenyl mercaptans iyanyibilika kwii-alcohols, ii-ethers, ii-esters kunye nezona zinyibilikisi zininzi ze-organic, kodwa ziphantse zinganyibiliki emanzini.
3. Ukuzinza: Kwiqondo lokushisa kwegumbi, i-prenyl mercaptans izinzile, kodwa ziya kubola phantsi kobushushu obuphezulu, i-asidi eqinile kunye neemeko ze-alkali ezinamandla.
Usetyenziso oluphambili lwe-prenyl mercaptans lulandelayo:
1. I-Organic synthesis: Njenge-intermediate in organic synthesis, isetyenziselwa ukulungiselela iiklasi ezahlukeneyo ze-organic compounds, ezifana ne-esters, i-ethers, i-ketones kunye ne-acyl compounds.
2. Ushishino lweziqholo: lusetyenziswa njengencasa neziqholo ukunika iimveliso ivumba elikhethekileyo lerayisi.
Kukho iindlela ezininzi zokulungiselela i-isopentenyl thiols, eziqhelekileyo ziquka:
1. Ifunyenwe kwi-reaction ye-pentadiene chloride kunye ne-sodium hydrosulfide.
2. Yenziwa ngokuphendula ngokuthe ngqo kwe-isopretenol kunye nezinto zesulfure.
1. I-Isopretenyl mercaptans iyacaphukisa kwaye kufuneka igwenywe ngokudibana ngqo nesikhumba kunye namehlo. Iiglavu ezikhuselayo kunye neglavu kufuneka zinxitywe xa usebenzisa.
2. Gwema ukudibana nee-oxidants ezinamandla, i-acids eqinile kunye ne-alkali enamandla ukuphepha ukuphendula okuyingozi.
3. Gcina kwisitya esingenawo umoya ukuze ugweme ukuvela emoyeni ukuthintela ukuguquguquka kunye nokulahlekelwa komsebenzi.
4. Sebenzisa kwindawo enomoya ococekileyo kwaye ugweme ukuphefumla imiphunga ye-isoprenyl mercaptan.
