Cyclopentene(CAS#142-29-0)
| Iikhowudi zoMngcipheko | I-R11 – Iyatsha kakhulu I-R21/22 – Iyingozi xa udibana nolusu kwaye ukuba uginyiwe. R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. I-R65 – Inobungozi: Inokubangela umonakalo emiphungeni ukuba iginyiwe R67 – Umphunga unokubangela ukozela kunye nesiyezi R52/53 – Iyingozi kwizinto eziphila emanzini, inokubangela iziphumo ezibi zexesha elide kwindawo ehlala emanzini. I-R38 – Iyacaphukisa ulusu |
| Inkcazelo yoKhuseleko | S9 – Gcina isikhongozeli kwindawo engenamoya. S16 – Gcina kude kwimithombo yomlilo. S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S33 -Thatha amanyathelo okhuseleko ngokuchasene nokukhutshwa okungatshintshiyo. S36 – Nxiba iimpahla ezifanelekileyo ezikhuselayo. S62 – Ukuba iginyiwe, musa ukugabha; funa iingcebiso zonyango ngokukhawuleza kwaye ubonise esi sikhongozeli okanye ileyibhile. S61 –Kuphephe ukukhutshelwa kokusingqongileyo. Jonga kwimiyalelo ekhethekileyo / kumaphepha edatha yokhuseleko. S36/37 – Nxiba iimpahla ezifanelekileyo zokukhusela kunye neeglavu. |

Intshayelelo
Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-cyclopentene:
Umgangatho:
1. I-Cyclopentene inevumba elimnandi kwaye iyanyibilika kwiintlobo ngeentlobo ze-solvents eziphilayo.
2. I-Cyclopentene yi-hydrocarbon engaxutywanga kunye ne-reactivity enamandla.
3. I-molecule ye-cyclopentene yi-five-membered annular structure kunye ne-curved conformation, ebangela uxinzelelo oluphezulu kwi-cyclopentene.
Sebenzisa:
1. I-Cyclopentene iyinto ebalulekileyo ekrwada kwi-organic synthesis, kwaye isoloko isetyenziselwa ukulungiswa kwee-compounds ezifana ne-cyclopentane, i-cyclopentanol, kunye ne-cyclopentanone.
2. I-Cyclopentene ingasetyenziselwa ukudibanisa izinto eziphilayo ezifana nedayi, iziqholo, irabha, kunye neeplastiki.
3. I-Cyclopentene iphinda isetyenziswe njengenxalenye ye-solvents kunye ne-extractants.
Indlela:
1. I-Cyclopentene idla ngokulungiswa nge-cycloaddition ye-olefins, njengokuqhekeza i-butadiene okanye i-oxidative dehydrogenation ye-pentadiene.
2. I-Cyclopentene nayo ingalungiswa nge-hydrocarbon dehydrogenation okanye i-cyclopentane dehydrocyclization.
Ulwazi ngoKhuseleko:
1. I-Cyclopentene i-liquid evuthayo, ekwazi ukutshabalalisa i-deflagration xa ibonakaliswe kwidangatye elivulekileyo okanye ukushisa okuphezulu.
2. I-Cyclopentene inefuthe elicasulayo emehlweni kunye nesikhumba, ngoko kufuneka ubeke ingqalelo ekukhuseleni.
3. Gcina umoya omhle xa usebenzisa i-cyclopentene ukuze ugweme ukuphefumla umphunga wayo.
4. I-Cyclopentene kufuneka igcinwe kwindawo epholileyo, epholileyo, kude nemithombo yomlilo kunye ne-oxidants.
