Ukuhlaziywa kwethemba lokuthuthukiswa kwemakethe ye-furfuryl alcohol

I-Furfuryl alcohol iyinto ebalulekile yamakhemikhali ephilayo.Isetshenziswa kakhulu ekukhiqizeni izakhiwo ezahlukahlukene ze-furan resin,utshwala furfurylI-urea formaldehyde resin kanye ne-phenolic resin. I-Hydrogenation ingakhiqiza i-tetrahydrofurfuryl alcohol, okuyi-solvent enhle ye-varnish, i-pigment kanye ne-rocket fuel. Ngaphezu kwalokho, ingasetshenziswa futhi ku-synthetic fiber, irabha, i-pesticide kanye nemboni yokuphonsa.

I-Furfuryl alcohol ayisetshenziswa nje kuphela njengento eluhlaza ye-furan resin, kodwa futhi njengodayi, i-varnish, i-phenolic resin, i-solvent noma i-disperant ye-furan resin, i-ejenti yokumanzisa, njll.Ukumelana okubandayo kwe-plasticizer eyenziwe ngayo kungcono kunotshwala be-butyl nama-octanol esters.

Ukusebenzisa i-furfural njengempahla eluhlaza kungaphinda kukhiqize ukucutshungulwa kabusha, njengokukhiqizwa kwe-furfural resin kanye nokukhiqizwa kwemikhiqizo ye-furfural hydrogenated. Imikhiqizo ebizwa ngokuthi i-furfural hydrogenated ibhekisela ku-furfural endaweni ethile yokushisa, i-catalyst kanye nezimo zenani le-pH, ingasabela nge-hydrogen ukuze ikhiqize i-tetrahydrofuran, i-furfuran alcohol nezinye izinto, ingaba yi-condensation eyengeziwe ukuze ikhiqize i-furan resin, esetshenziswa kabanzi emishini imboni yamakhemikhali.

I-Furfuryl alcohol, eyaziwa nangokuthi i-furfuryl alcohol, iyinto ebalulekile yamakhemikhali ephilayo. Ukukhiqizwa kwayo ezimbonini kwaqala ukubonwa yi-Quaker Oats Company ngo-1948. I-Furfuryl alcohol iyingxenye ebalulekile ye-furfural, elungiswa nge-catalytic hydrogenation of furfural in gas or liquid phase. I-Furfural ingenziwa ngokuqhekeka kanye nokuqeda amanzi e-pentose emfucumfucwini yezitshalo njengezikhwebu zommbila, izinsalela ze-sucrose, amakhoba embewu kakotini, izinhlanga zikabhekilanga, amakhoba kakolo namakhoba elayisi.

I-Furfuryl alcohol iwumkhiqizo oyinhloko we-furan resin. Imikhiqizo yayo ihlanganisa: i-urea-formaldehyde furan resin, i-phenolic furan resin, i-keto-aldehyde furan resin, i-urea-formaldehyde phenolic furan resin. I-resin isetshenziswa kakhulu ekubunjweni nasekwenzeni okuphakathi. I-Furfuryl alcohol nayo ingasetshenziswa njenge-antiseptic resin, izinto zokusetshenziswa kwemithi.

I-furfural alcohol isetshenziswa kakhulu ekukhiqizweni kwe-furfural resin, furfural resin, furfural alcohol - umchamo we-aldehyde resin, i-phenolic resin, njll. Ibuye isetshenziselwe ukulungisa i-asidi yezithelo, i-plasticizer, i-solvent kanye ne-rocket fuel. Ngaphezu kwalokho, kumadayi, imicu yokwenziwa, irabha, izibulala-zinambuzane, ukuphonsa neminye imikhakha yezimboni nayo isetshenziswa kabanzi.
