3. Ukunambitha: ngenxa yephunga le-fruity yalo, kusetshenziswa ukunambitheka embonini yokudla.
I-4. Solvent: Kungasebenza njenge-solvent ekuphendukeni okuhlukahlukene kwamakhemikhali nezinqubo.
I-5. Amadayi kanye nemibala: I-methyl acetoacetate nayo isetshenziswa ekukhiqizweni kwamadayi athile nemibala.
6. Ucwaningo: Isetshenziswa ezindaweni zokucwaninga ngezinhloso zocwaningo, ikakhulukazi izifundo ezibandakanya ama-organic chemistry kanye nezindlela zokuphendula.
Kuyancibilika emanzini, incibilika kakhulu ezinhlafunweni eziningi ze-organic.
1. Gcina endaweni yokugcina izinto epholile, enomoya. Gwema kude nomlilo nemithombo yokushisa. Kufanele igcinwe ngokwahlukana ne-oxidants kanye nezisekelo eziqinile, futhi igweme isitoreji esixubile. Ifakwe ngezinhlobonhlobo ezifanele nenani lemishini yomlilo. Indawo yokugcina kufanele ifakwe imishini yokuvuza yokwelashwa okuvuzayo nezinto zokugcina ezifanele.
2. Lo mkhiqizo ugcwele izigubhu ze-aluminium. Qaphela ukuthi isembozo sivalwe kahle. Gcina endaweni epholile futhi enomoya. Ukuvimbela Umlilo. Gcina futhi uthumele ngokuhambisana nemigomo yamakhemikhali avuthayo futhi anobuthi.
1. Isitsha: Gcina esitsheni esivalwe ukuvimba ukuhwamuka nokungcola. Sebenzisa iziqukathi ezenziwe ngezinto ezihambelana ne-organic solvents, njengengilazi noma amapulasitiki athile.
2. Ukushisa: Sicela uyigcine endaweni epholile neyomile, kude nokukhanya kwelanga okuqondile nemithombo yokushisa. Ngokufanelekile, kufanele igcinwe emazingeni okushisa asekamelweni noma esiqandisini, kuya ngezidingo ezithile.
3. Ukuphefumula umoya: qiniseka ukuthi indawo yokugcina inomoya omuhle ukugwema ukunqwabelana kwe-vapor.
4. Ukungalingani: Gcina kude ne-oxidants eqinile, ama-acid kanye nezisekelo njengoba zizosabela nge-methyl acetoapetate.
I-5. Ilebula: Faka ilebula ngokucacile iziqukathi ngegama lamakhemikhali, okuhlushwa, kanye nemininingwane yengozi.
I-6
1. Gwema ukuxhumana ne-oxidants. Kuyinto evuthayo, futhi ingacishwa ngesifutho samanzi, i-ejenti yokucima i-powder, i-carbon dioxide, njll lapho ibamba umlilo.
Izakhiwo zamakhemikhali: obomvu obumnyama uma kwenzeka ku-forric chloride. Ibilisiwe ngamanzi futhi ibolile ibe yi-acetone, i-methanol ne-carbon dioxide.
2. Lo mkhiqizo awunazo ubuthi obunobuthi, i-rat oral ld503.0g / kg. Amagundane avezwa umusi ohlanganisiwe amahora angama-8, kepha akukho kufa okutholakele. Kuyinto ecasulayo futhi i-narcotic. Ukuqina komoya kwemishini kanye nomoya omncane wendawo yokusebenza kufanele kuqiniswe. Ama-opharetha agqoka imishini yokuvikela.
1. Ukulandela umthetho wokulawula: Qinisekisa ukuhambisana nemithetho yendawo, kazwelonke, kanye neyamazwe omhlaba maqondana nokuhamba kwezinto eziyingozi. I-methyl acetoacetate ingahlukaniswa njengoketshezi oluvuthayo ngakho-ke ngokuya ngemithetho ethile yokuhamba.
2. Ukulebula okufanele
3. Ukupakishwa: Sebenzisa izinto ezisebenza kahle zokufaka ezihambelana ne-methyl acetoacetate. Lokhu ngokujwayelekile kuzofaka ukusetshenziswa kweziqukathi ezivunyiwe ze-UN ezingamelana nokuvuza okungaba khona noma ukuchitheka.
4. Ukulawulwa kokushisa: Uma kunesidingo, qinisekisa ukuthi izimo zokuhamba zigcina izinga lokushisa elizinzile ukuvikela ukonakala noma ushintsho ezinhlakeni zamakhemikhali zento.
I-5. Imibhalo: Lungiselela futhi ufake yonke imibhalo edingekayo yokuthumela efana nephepha lokuphepha (SDS), Isimemezelo Sokuhambisa, kanye nanoma yimiphi eminye imibhalo efanelekile.

7. Impendulo ephuthumayo: Yiba nohlelo lokuphendula oluphuthumayo lukhona uma kwenzeka ukuvuza noma ukuchitheka ngesikhathi sokuhamba. Lokhu kufaka ukuba nekhithi yokuchitheka kanye nemishini efanelekile yokuzivikela (i-PPE) isilungile.
Yebo, i-methyl acetoacetate ibhekwa njengengozi. Nawa amanye amaphuzu asemqoka ngezingozi zawo:
1. Ukuvuselelwa: I-methyl acetoacetate iyavutha futhi ingahle ibe nengozi yomlilo uma kuvezwa amazinga okushisa aphezulu, izinhlansi noma amalangabi avulekile. Inephuzu le-flash elicishe libe ngu-50 ° C (122 ° F).
2. Ingozi yezeMpilo: Ukuchayeka ku-methyl acetoacetate kungahle kukucasule isikhumba, amehlo kanye nohlelo lokuphefumula. I-inhalation of vapors ingadala amakhanda, isiyezi noma isicanucanu. Ukuvezwa isikhathi eside noma okuphindaphindwayo kungadala imiphumela emibi yempilo.
I-3. Ingozi Yezemvelo: Kungaba yingozi empilweni yasemanzini futhi kufanele kusingathwe ngendlela ukuvimbela ukukhululwa emvelweni.
4. Ukuhlukaniswa kokulawula: Ngokuya ngemithethonqubo ethile endaweni yangakini, kungenzeka ukuthi i-acetoacetate ye-methyl ingahlukaniswa njengokuqukethwe okuyingozi okudinga ukuphathwa okukhethekile, ukugcinwa kanye nezinqubo zokuhamba.
