Intshayelelo
I-4-Pentyny-1-ol, eyaziwa ngokuba yi-hexynyl alcohol. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-4-pentynyn-1-ol:
Umgangatho:
I-4-Pentoyn-1-ol lulwelo olungenambala ukuya kumthubi olunevumba elikhethekileyo. Yikhompawundi engazinzanga ethanda ukwenza iipolymerize okanye isabele ngokwayo.
Sebenzisa:
I-4-Pentyne-1-ol ineempawu ze-alkyne kwaye ingasetyenziselwa ukuhlanganiswa kwamanye ama-organic compounds. Ihlala isetyenziswa njengendawo ephakathi kwi-organic synthesis kwaye ingasetyenziselwa ukulungisa i-ethers, i-esters, i-aldehydes kunye nezinye iikhompawundi.
Indlela:
Kukho iindlela ezininzi zokulungiselela i-4-pentin-1-ol. Indlela eqhelekileyo kukusabela i-1,2-dibromoethane kunye ne-sodium ethanol ukuvelisa i-pentynylethanol, kwaye emva koko ulungiselele i-4-pentin-1-ol nge-hydrogenation reaction.
Ulwazi ngoKhuseleko:
I-4-Pentoyn-1-ol ayizinzile kwaye ithande ukusabela ngokuzimeleyo, kwaye idinga ukuphathwa ngononophelo xa iphathwa. Iyakwazi ukutsha kwaye ithanda ukugqabhuka kwimixube xa isesichengeni somlilo ovulekileyo okanye amaqondo obushushu aphezulu. Ukudibana nolusu okanye amehlo kunokubangela ukudumba kunye nokucaphuka, kwaye amanyathelo okuzikhusela afana neeglavu kunye nezibuko kufuneka athathwe xa kusenziwa njalo. Sebenza kwindawo engenamoya kwaye kude nomlilo. Ukuba uphefumlelwe okanye ukutyile, funa unyango ngokukhawuleza. Nceda ulandele iinkqubo zokusebenza ezikhuselekileyo zokusetyenziswa ngokufanelekileyo.
