| Gukemura | irashobora gukuramo hydrogen sulfide, aside hydrocyanic, dioxyde de sulfure.Irashobora kwibeshya n'amazi, Ethanol, igice 1 cyibicuruzwa birashobora gushonga mubice 11 bya Ethyl acetate, ibice 500 bya ether, bitangirika muri benzene, carbone disulfide, trichloromethane, karubone tetrachloride, peteroli ether, chloroform, amavuta.Byoroshye kubura amazi, gutakaza amazi kugirango bibe bis-glycerol na polyglycerol, nibindi .. Oxidation yo kubyara glycerol aldehyde na aside glycerol.Ikomera kuri 0 ° C, ikora kristu ya rhombohedral hamwe na glitter.Polymerisation ibaho ku bushyuhe bwa 150 ° C.Ntushobora guhuzwa na anhydride ya anhydrous anhydride, potasiyumu permanganate, acide ikomeye, ruswa, amine amavuta, isocyanates, okiside. |
Ibisobanuro ku bicuruzwa:
Glycerine, izwi nka glycerol mubipimo byigihugu, ni ibara, impumuro nziza, iryoshye-impumuroingingo ngengabuzima hamwe nigaragara ryamazi meza.Bisanzwe bizwi nka glycerol.Glycerol, irashobora gukuramo ubuhehere buturuka mu kirere, ariko kandi ikurura hydrogène sulfide, hydrogen cyanide na dioxyde de sulfure.
Ibicuruzwa byiza nibihamye:
1.Ibara ritagira ibara, rifite umucyo, ridafite impumuro nziza, amazi meza afite uburyohe buryoshye hamwe na hygroscopicity.Ntibisanzwe n'amazi na alcool, amine, fenol muburyo ubwo aribwo bwose, igisubizo cyamazi ntaho kibogamiye.Gukemura inshuro 11 Ethyl acetate, inshuro 500 ether.Kudashonga muri benzene, chloroform, karubone tetrachloride, karubone disulfide, ethers ya peteroli, amavuta, inzoga ndende zinzoga.Kwaka, birashobora gutera gutwikwa no guturika mugihe uhuye ningingo zikomeye za okiside nka dioxyde de chromium na chlorate ya potasiyumu.Numuti mwiza kandi mwinshi kuri myunyu ngugu na gaze.Kudashobora kwangirika kwibyuma, birashobora guhinduka okiside kuri acroleine mugihe ikoreshwa nkibishishwa.
2.Imiterere ya chimique: reaction ya esterification hamwe na aside, nka esterifike ya benzene dicarboxylic kugirango itange alkyd resin.Transesterification reaction hamwe na ester.Igisubizo hamwe na hydrogène chloride kugirango ikore alcool ya chlorine.Umwuma wa Glycerol ufite inzira ebyiri: umwuma wa intermolecular kugirango ubone diglycerol na polyglycerol;umwuma wa intramolecular kugirango ubone acrolein.Glycerol ifata ibyingenzi kugirango ibe inzoga.Igisubizo hamwe na aldehydes na ketone bitanga acetal na ketone.Oxidation hamwe na acide ya nitricike itanga glyceraldehyde na dihydroxyacetone;okiside hamwe na aside irike itanga aside irike na fordehide.Hamwe na okiside ikomeye nka chromic anhydride, potasiyumu chlorate cyangwa potasiyumu permanganate, bishobora gutera gutwikwa cyangwa guturika.Glycerol irashobora kandi kugira uruhara rwa nitrification na acetylation.
3.Nta burozi.Nubwo ingano yuzuye yo kunywa igera kuri 100g yumuti wa dilute ntacyo itwaye, mumubiri nyuma ya hydrolysis na okiside hanyuma bigahinduka intungamubiri.Mu bushakashatsi bw’inyamaswa, bugira ingaruka za anesteziya nkinzoga iyo ikozwe kunywa byinshi.
4.Ibikorwa byo guteka itabi, itabi ryimbavu ryera, itabi ryibirungo, numwotsi w itabi.
5.Ibisanzwe mubitabi, byeri, vino, cakao.
Gusaba ibicuruzwa:
1. Resin inganda: ikoreshwa mugukora alkyd resin na epoxy resin.
2. Inganda zitwikiriye: zikoreshwa mu nganda zo gutwika mu gukora ibinyobwa bitandukanye bya alkyd, resin polyester, glycidyl ethers na epoxy resin, nibindi.
3. Inganda zo gucapa no gucapa no gusiga amarangi: zikoreshwa mugukora amavuta, kwinjiza amazi, imiti yo kugabanya imiti igabanya ubukana, imiti ikwirakwiza no kwinjira.
Uburyo bwo kubika ibicuruzwa:
1. Bika ahantu hasukuye kandi humye, ugomba kwitondera ububiko bwafunzwe.Witondere kutagira amazi, kutagira amazi, exothermic, kubuza rwose kuvanga na okiside ikomeye.Irashobora kubikwa mumabati cyangwa amabati.
2. Bipakiye mu ngoma ya aluminium cyangwa ingoma ya fer ya galvanis cyangwa ibitswe mu bigega byometse kuri resinike.Igomba kurindwa ubushuhe, ubushyuhe namazi mugihe cyo kubika no gutwara.Birabujijwe gushyira glycerol hamwe ningingo zikomeye za okiside (urugero aside aside, potasiyumu permanganate, nibindi).Igomba kubikwa no gutwarwa hakurikijwe amategeko rusange y’imiti yaka umuriro.
Inyandiko zibika ibicuruzwa:
1.Bika mububiko bukonje, buhumeka.
2.Komeza kure yumuriro nubushyuhe.
3.Komeza ikintu gifunze.
4.Bigomba kubikwa bitandukanye na okiside, kugabanya imiti, alkalis hamwe nimiti iribwa, ntukavange ububiko.
5.Yahawe ibikoresho bitandukanye nubwinshi bwibikoresho byo kurwanya umuriro.
6.Ahantu ho guhunika hagomba kuba hafite ibikoresho byihutirwa byihutirwa nibikoresho byubuhungiro.
