I-1.Inokunambitheka kokudla, okusetshenziselwa ikakhulukazi ukulungiswa kwezinambuzane zezithelo ezinjengamapheya, ama-apula, amagilebhisi nama-cherries.
2.Kusetshenziswa kabanzi ekuhlanganiseni kwe-barturic acid, amavithamini acid, amavithamini B1, B2 kanye b6, izidakamizwa zokulala kanye ne-phenylbutazone.
I-3.isetshenziswe kabanzi kwamanye ama-Chemical Production Fields, kufaka phakathi ama-pesticides, amadayi wezimboni, izinto zekristalu eziwuketshezi, njll.

I-6. Ukulungiselela ama-acid β-keto: β-keto acid kungahlanganiswa ngenqubo ebizwa nge-alkylation.
7. Ukukhiqizwa kwe-heterocyclic compounds: I-Diethyl Malonate isetshenziswa ekuhlanganiseni kwamakhompiyutha we-heterocyclic, abalulekile kumakhemikhali wezokwelapha.
8. Ukutholwa kanye nesinongo: Ngenxa yephunga layo lezithelo, kungasetshenziswa futhi embonini yokudla kanye ne-spice.
Kuyancibilika ku-chloroform, benzene nakwezinye izixazululo ze-organic. Incibilika kancane emanzini.
1. Gcina endaweni yokugcina izinto epholile, enomoya. Gwema kude nomlilo nemithombo yokushisa. Kufanele igcinwe ngokwahlukana ne-oxidants, i-alkalis eqinile, kanye nokunciphisa ama-ejenti, futhi igweme isitoreji esixubile. Ifakwe ngezinhlobonhlobo ezifanele nenani lemishini yomlilo. Indawo yokugcina kufanele ifakwe imishini yokuvuza yokwelashwa okuvuzayo nezinto zokugcina ezifanele.
2. Gcina futhi uthuthe ngokuhambisana nemigomo yamakhemikhali avuthayo.
1. Isitsha: Store dieethyl malonate esitsheni esivalwe ukuvimba nokuhwamuka. Sebenzisa iziqukathi ezenziwe ngengilazi noma ngepulasitiki ehambisanayo.
2. Ukushisa: Sicela uyigcine endaweni epholile neyomile, kude nokukhanya kwelanga okuqondile nemithombo yokushisa. Ngokufanelekile, kufanele igcinwe emazingeni okushisa asekamelweni noma esiqandisini uma kudingeka isitoreji eside.
3. I-inert gesi: Uma kungenzeka, gcina ngaphansi kwegesi i-inert enjenge-nitrogen noma i-argon ukunciphisa ukuvezwa komswakama nomoya, okungadala i-hydrolysis noma i-oxidation.
4. Ilebula: Faka ilebula ngokucacile iziqukathi ngegama lamakhemikhali, okuhlushwa, kanye nosuku lokugcina ukuze uqinisekise ukuhlonza okufanele nokuphatha.
I-5
1. Gwema ukuxhumana ne-oxidants, ukunciphisa ama-ejenti kanye ne-alkalis. Izakhiwo zamakhemikhali zizinze kakhulu kune-diethelyl oxalate. Njengoba ine-hydrolyzed kalula ukukhiqiza i-magonic acid, okudingeka kakhulu ukuvikela ukuphefumula komoya noma ukuxhumana nesikhumba.
2. Lo mkhiqizo unobuthi obuphansi, i-rat oral ld50> 1600mg / kg, kepha izokwenziwa i-acid emzimbeni, gwema ukuxhumana. Geza ngemuva koxhumana naye. Ama-opharetha kufanele agqoke amagilavu enjoloba.
1. Ukulandela umthetho wokulawula: Qinisekisa ukuthi uhambisana nayo yonke imithetho yendawo, kazwelonke neyamazwe jikelele mayelana nokuhamba kwamakhemikhali. Lokhu kungafaka ukulebula okufanele, amadokhumenti kanye nokuhambisana nemigomo eyingozi yezinto zokwenziwa.
2. Ukupakishwa: Sebenzisa izinto ezisebenza kahle zokufaka ezihambelana ne-Diethyl Malonate. Isitsha kufanele sivuze futhi senziwe ngezinto ezingenziwanga ngamakhemikhali. Qiniseka ukuthi ukufakwa kuqinile ngokwanele ukumelana nokuphatha ngesikhathi sokuhamba.
3. Ukulawulwa kokushisa: gcina izinga lokushisa le-diethell malonate esitebeleni ngesikhathi sokuhamba. Gwema ukudalulwa kwamazinga okushisa aphezulu, azothinta ubuqotho bamakhemikhali.
4. I-inert gesi: Uma kungenzeka, i-diethelylote malonate kufanele ithuthwe ngendlela enciphisa ukubonwa kwayo emoyeni nomswakama, ngoba lokhu kungakubangela ukungcola.
I-5. Imishini yokuzivikela (i-PPE): Qinisekisa ukuthi abasebenzi ababhekele ukuthutha i-Diethellote Malonate bagqoke i-PPE efanelekile, kufaka phakathi amagilavu, ama-goggles kanye nezingubo zokuvikela ukuvimbela isikhumba nokubonana ngamehlo.
6. Izinqubo eziphuthumayo: Yiba nezinqubo eziphuthumayo endaweni uma kwenzeka kuchitheka noma ukuvuza kwenzeka ngesikhathi sokuhamba. Lokhu kufaka nokuba nekhithi elachitheka ngaso sonke isikhathi kanye nokuqinisekisa abasebenzi baqeqeshelwe impendulo ephuthumayo.
