Intshayelelo
iimpawu zeekhemikhali
Ulwelo olungenambala olucacileyo olunokutsha olunevumba le-aldehyde elinukayo. Inyibilika kancinane emanzini. Ixutywe ne-ethanol, i-ether, i-ethyl acetate, i-acetone, i-toluene, iindidi zezinye izinyibilikisi eziphilayo kunye namafutha.
Sebenzisa
Isetyenziswa kwi-organic synthesis kunye nemathiriyeli ekrwada yokwenza iziqholo
Sebenzisa
I-GB 2760-96 ichaza iziqholo ezityiwayo ezivumelekileyo ukuba zisetyenziswe. Ikakhulu isetyenziselwa ukulungiselela iibhanana, i-caramel kunye nezinye iziqhamo zeziqhamo.
Sebenzisa
ibutyraldehyde yinto ebalulekileyo ephakathi. i-n-butanol inokuveliswa nge-hydrogenation ye-n-butanal; I-2-ethylhexanol inokuveliswa ngokuchithwa kwe-condensation kunye ne-hydrogenation, kunye ne-n-butanol kunye ne-2-ethylhexanol yizona zinto ziphambili zeplastiki. i-n-butyric acid inokuveliswa nge-oxidation ye-n-butyric acid; i-trimethylolpropane inokuveliswa nge-condensation kunye ne-formaldehyde, eyi-plasticizer ye-synthesis ye-alkyd resin kunye ne-raw material ye-air drying oil; i-condensation kunye ne-phenol ukuvelisa i-oil-soluble resin; ukuxinana nge-urea kunokuvelisa intlaka enyibilikayo ngotywala; iimveliso ezixutywe nge-polyvinyl alcohol, i-butylamine, i-thiourea, i-diphenylguanidine okanye i-methyl carbamate zizinto eziluhlaza kunye, ukuxinzeliswa kwee-alcohols ezahlukeneyo kusetyenziswa njenge-solvent ye-celluloid, i-resin, i-rubber kunye nemveliso yamayeza; ishishini lamachiza lisetyenziselwa ukwenza "Mianerton", "pyrimethamine", kunye ne-amylamide.
Sebenzisa
Iglue yerabha, i-accelerator yerabha, i-synthetic resin ester, i-asidi ye-butyric, njl njl. Isisombululo sayo se-hexane yi-reagent yokumisela i-ozone. Isetyenziswe njenge-solvent ye-lipids, iphinda isetyenziswe ekulungiseleleni i-flavour kunye ne-fragrances kunye ne-preservative.
Indlela yokuvelisa
okwangoku, iindlela zokuvelisa i-butyraldehyde zamkela ezi ndlela zilandelayo: 1. ipropylene carbonyl synthesis method propylene kunye ne-synthesis gas iqhuba i-carbonyl synthesis reaction phambi kwe-Co okanye i-Rh catalyst ukuvelisa i-n-butyraldehyde kunye ne-isobutyraldehyde. Ngenxa yeendlela ezahlukeneyo ze-catalysts kunye neemeko zenkqubo ezisetyenzisiweyo, inokwahlulwa ibe yi-high-pressure carbonyl synthesis kunye ne-cobalt carbonyl njenge-catalyst kunye ne-low-pressure carbonyl synthesis kunye ne-rhodium carbonyl phosphine complex njenge-catalyst. Indlela yoxinzelelo oluphezulu inoxinzelelo oluphezulu lokusabela kunye neemveliso ezininzi, ngaloo ndlela inyusa iindleko zemveliso. Indlela ephantsi yoxinzelelo lwe-carbonyl synthesis inoxinzelelo oluphantsi lokuphendula, umlinganiselo ochanekileyo we-isomer we-8-10: 1, ngaphantsi kweemveliso, izinga eliphezulu lokuguqulwa, izinto eziphantsi, ukusetyenziswa kwamandla aphantsi, izixhobo ezilula, inkqubo emfutshane, ebonisa iziphumo ezibalaseleyo zoqoqosho kunye uphuhliso olukhawulezayo. 2. Indlela ye-acetaldehyde condensation. 3. Indlela ye-butanol oxidative dehydrogenation isebenzisa isilivere njenge-catalyst, kwaye i-butanol i-oxidized emoyeni kwinqanaba elinye, kwaye emva koko i-reactants iyancitshiswa, ihlukaniswe, kwaye ilungiswe ukuze ifumane imveliso egqityiweyo.
Indlela yokuvelisa
Ifunyaniswa ngedistillation eyomileyo ye-calcium butyrate kunye ne-calcium formate.
Umphunga ufunyenwe ngokukhutshwa kwe-dehydrogenation ye-catalyst.
