Intshayelelo emfutshane
I-2-Methyl-2-pentenal ikwabizwa ngokuba yi-prenal okanye i-hexenal. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwekhompawundi:
Umgangatho:
I-2-Methyl-2-pentenal lulwelo olungenambala kunye nevumba elimnandi elingaqhelekanga. Lulwelo olunganyibilikiyo emanzini kwaye lunyibilika kwizinyibilikisi ezininzi zezinto eziphilayo. Kwiqondo lobushushu begumbi, inoxinzelelo oluphantsi lomphunga.
Sebenzisa:
I-2-Methyl-2-pentenal inoluhlu olubanzi lwezicelo zoshishino. Isenokusetyenziswa njenge-rubber processing aid, irabha antioxidant, i-resin solvent, njl.
Indlela:
Ukulungiswa kwe-2-methyl-2-pentenal idla ngokufunyanwa ngokusabela kwe-isoprene kunye ne-formaldehyde. Amanyathelo athile aqhelekileyo ngolu hlobo lulandelayo: phambi kwe-catalyst efanelekileyo, i-isoprene kunye ne-formaldehyde zongezwa kwi-reactor ngomlinganiselo othile kwaye zigcinwe kwiqondo lokushisa elifanelekileyo kunye noxinzelelo. Emva kokuba i-reaction iqhutywe ixesha elithile, i-2-methyl-2-pentenal ehlambulukileyo inokufumaneka ngeendlela zenkqubo ezifana nokukhupha, ukuhlamba amanzi, kunye ne-distillation.
Ulwazi ngoKhuseleko:
I-2-Methyl-2-pentenal yikhemikhali enzima enokucaphukisa amehlo, ulusu kunye nokuphefumula xa kubonakaliswe. Nxiba izixhobo ezifanelekileyo zokukhusela xa usebenza kwaye uphephe ukudibana ngokuthe ngqo kangangoko kunokwenzeka. Kwakhona i-liquid enokutsha kwaye kufuneka ikhuselwe ekudibaneni nokushisa okuphezulu, amadangatye avulekileyo kunye ne-oxidizing agents. Kwimeko yokuvuza ngengozi, amanyathelo afanelekileyo kufuneka athathwe ngokukhawuleza ukuyicoca kunye nokulahla.
