Furfural ndiyo mbishi yefurfuryl doro, iyo inowanikwa nekuputika uye kuderedza mvura yepolypentose iri mune zvekurima uye parutivi zvigadzirwa. Furfural is hydrogenated todoro rinodhakapasi pemamiriro e catalyst, uye ndiyo huru mbishi yekugadzira furfuran resin.Furfuryl dorochinhu chakakosha organic makemikari raw material. Vashandisi vakuru vanogadzira furfural resin, furfuran resin, furfuryl alcohol - urea formaldehyde resin, phenolic resin, etc. Inoshandiswawo kugadzira michero acid, plasticizer, solvent uye rocket fuel. Uye zvakare, inoshandiswa zvakanyanya muzvikamu zveindasitiri senge mafuta, synthetic fibers, rabha, mishonga yezvipembenene nekukanda. Panguva imwecheteyo inogona kugadzira plasticizer, kutonhora kuramba kuri nani pane butyl doro uye octanol esters. Calcium gluconate inogadzirwa. Synthesis yedhayi, mishonga yepakati, kugadzirwa kwemakemikari epakati, kugadzirwa kwepyridine.
Tsanangudzo: Mvura isina ruvara inoyerera zviri nyore, inoshanduka shava kana yakadzika yakatsvuka kana yakafumurwa nechiedza chezuva nemhepo. Inonaka inovava.
Solubility: inogona kusanganiswa nemvura, asi isina kugadzikana mumvura, inonyungudika mu ethanol, ether, benzene uye chloroform, isinganyunguriki mupetroleum hydrocarbons.
Emergency nzira:
Leakage treatment
Bvisa vashandi kubva munzvimbo yakasvibiswa kuenda kunzvimbo yekuchengetedza, rambidza vashandi vasina basa kuti vapinde munzvimbo ine utachiona, uye cheka nzvimbo yemoto. Emergency responders vanorayirwa kuti vapfeke zvidzitiro zvekufema zvega uye zvipfeko zvinodzivirira zvemakemikari. Usabate iyo inodonha zvakananga, kuitira kuti uve nechokwadi chekuchengetedzwa kwekudonha. Pfaya mvura kuderedza kubuda. Yakasanganiswa nejecha kana imwe isingabatike adsorbent yekunyura. Inobva yaunganidzwa yoendeswa kunzvimbo inorasirwa marara kuti inoraswa. Inogonawo kushambidzwa nemvura yakawanda uye yakanyungudutswa mumvura yakasvibiswa. Zvakadai sehuwandu hukuru hwekuvuza, kuunganidza uye kudzokorodza kana kuraswa kusina njodzi mushure memarara.
Nzira yekurasa tsvina: nzira yekupisa, marara yakasanganiswa neanopisa zvinonyungudutsa mushure mekupisa.
Matanho ekudzivirira
Dziviriro yekufema: Pfeka chifukidziro chegasi kana zvichikwanisika kubata nemhute yaro. Pfeka kufema kwega panguva yekununura kana kutiza.
Dziviriro yeziso: Pfeka magirazi ekuchengetedza.
Zvipfeko zvinodzivirira: Pfekai zvipfeko zvinodzivirira zvakakodzera.
Vamwe: Kusvuta, kudya uye kunwa zvinorambidzwa panzvimbo. Mushure mekushanda, nyatsogeza. Chengeta mbatya dzine muchetura woga wogeza usati wadzishandisa. Ngwarira utsanana hwemunhu.
First aid chiyero
Kubata ganda: Bvisa hembe dzine utachiona uye ipapo wonyatsogeza nemvura inoyerera.
Kubata maziso: Simudza pakarepo eyelid wonyatsogeza nemvura yakawanda inoyerera.
Inhalation: Kurumidza kubvisa kubva panzvimbo kuenda kumhepo itsva. Chengetedza nzira yako yemhepo yakachena. Ipa oxygen kana kufema kwakaoma. Kana kufema kwamira, ipa kufema kwekugadzira nekukasika. Tsvaka kurapwa.
Kudya: Kana murwere akamuka, inwa mvura yakawanda inodziya kuti utange kurutsa uye kutsvaga kurapwa.
Nzira yekudzima moto: mvura yemhute, furo, hupfu hwakaoma, carbon dioxide, jecha.
Kurongedza uye kuchengetedza: Kurongedza mumadhiramu esimbi, 230kg, 250kg padhiramu. Chengeta munzvimbo inotonhorera, yakaoma uye ine mhepo yakanaka. Mafireworks anorambidzwa zvachose. Usachengete uye kutakura neakasimba acids, yakasimba oxidizing makemikari uye chikafu.
