Tuhinga o mua

I te 1832, ko te kaimana Tiamana a Johann Wolfgang D? Bereiner, te tuatahi i wehe i te huruhuru, i hangaia e ia tetahi waahanga tino iti hei hua o te waihanga waikawa formic. 
I te tau 1840, i kitea e te kaimana o Kotimana a John Stenhouse ka taea te whakaputa i taua matū ma te tohatoha i nga momo momo hua tipu, tae atu ki te parani, te kānga, te otaota, me te otaota, me te waikawa pungatara waipiro, a ka whakatauhia e ia he tikanga whai tikanga tenei matū. Tuhinga o mua5H4E2
I te 1901, i tangohia e te kaimana o Tiamana, a Carl Harries, te hanganga o te furfural.

Nga Tikanga Takitari Furfural

Mo te taatai ​​matū mahi whakamahia OSHA: # ID-72 ko NIOSH: Furfural, 2529.

Whakatakotoranga Furfural

Ko te Furfural he aldehyde heterocyclic, me te hanganga mowhiti e whakaaturia ana i te taha matau. Ko tana tikanga matū ko te OC4H3CHO He wai hinuhinu korekore nei he haunga aramona, engari ka kitea ana he tauira kowhiri ka kowhai tonu. Me te CAS KORE. 98-01-1, Ka rewa noa te Furfural i roto i te nuinga o nga whakarewa waro, engari he paku wairewa noa i roto i te wai, i nga wai waikore ranei. Ka wera ana i runga ake i te 250 ° C, ka huri te huruhuru ki te furan me te waro monoxide, i etahi waa ka pupuhi.

Nga taonga a-tinana Furfural ko:
(1) ACD / Rangitaki: 0.731; (2) ACD / Takiuru (pH 5.5): 0.73; (3) ACD / Takiuru (pH 7.4): 0.73; (4) ACD / BCF (pH 5.5): 2.12; (5) ACD / BCF (pH 7.4): 2.12; (6) ACD / KOC (pH 5.5): 59.53; (7) ACD / KOC (pH 7.4): 59.53; (8) Nga kaiwhiwhi hononga #H: 2; (9) Nga hononga hono e tere hurihuri ana: 1; (10) Tuhia te Whakauru: 1.515; (11) Molar Refractivity: 25.305 cm3; (12) Rawa Molar: 83.894 cm3; (13) Ngaohitanga Polariz: 10.032 10-24cm3; (14) Taumarutanga Papa: 36.5740013122559 dyne / cm; (15) Te Taumaha: 1.145 g / cm3; (16) Tohu Rama: 58.333 ° C; (17) Enthalpy o te Whakaweto: 39.837 kJ / mol; (18) Whewhe Tohu: 161.799 ° C i te 760 mmHg; (19) Ngaohikoohonga: 2.23399996757507 mmHg i te 25 ° C

Te whakarite i te Huruhuru:
He maha nga rauemi tipu kei roto i te hemicellulose polysaccharide, he polymer o nga huka kei roto e rima nga ngota waro o ia. Ka werahia ki te waikawa sulfuric, ka uru te hemicellulose ki te hydrolysis ki te whakaputa i enei huka, te tikanga he xylose. I raro i nga tikanga o te wera me te waikawa, ka mate te mate o te xylose me etahi atu huka waro e rima, ka ngaro te toru o nga ngongo waipiro kia huri haere:

C5H10E→ C5H4E+ 3 H2E

Whakamahinga Furfural:
Ka whakamahia te Furfural hei whakarewa i te whakamahine petrochemical ki te tango i nga diene (hei hanga i te rapa waihanga) mai i etahi atu hauwaiwaro. Ka taea hoki e te Furfural te whakamahi ma raatau, ma te taha o te phenol, te acetone, te urea ranei hei hanga i nga reini totoka. Kei te whakamahia ano hei takawaenga matū i te hanga o nga whakarewa furan me te tetrahydrofuran.

Nga korero haumaru mo Furfural:
I a koe e whakamahi ana i tenei matū, kia tupato kia penei: (1) Mena ka pa atu o kanohi, horoia tonu me te nui o te wai ka toro atu ki nga tohutohu hauora. (2) kakahuria nga kakahu tiaki e tika ana, nga karapu me te tiaki kanohi / kanohi; (3) Mena he aitua mena he ngoikore koe, rapua nga tohutohu hauora tonu (whakaatuhia te tapanga ki te taea); (4) Me raka kia kore e taea e nga tamariki te toro atu;

Ka taea tonu e koe te huri i nga waahanga e whai ake nei hei hanganga ngota:
(1) InChI = 1S / C5H4O2 / c6-4-5-2-1-3-7-5 / h1-4H;

(2) InChIKey = HYBBIBNJHNGZAN-UHFFFAOYSA-N;
(3) Smilesc1 (ccco1) C = O;
