3.R zvakare inoshandiswa zvakanyanya mune mamwe emakemikari ekugadzira minda, kusanganisira zvipembenene, maindasitiri madhiri, mvura yemvura, nezvimwe zvinhu.
4. Kuvaka mabhuruku mune synthesis: zvinowanzoshandiswa senge precursor mune synthesis yemakomputa akasiyana-siyana, kusanganisira mishonga mishonga, gentomicals, uye dhayi.
5. Malallesis: Diethyl Mallesis anowanzo shandiswa muMalonate Synthesis, iyo inzira yekugadzira carboxylic acids uye nhaka yavo.
6. Kugadzirira kwe β-keto acids: β-keto acids kunogona kuvezwa kuburikidza nemaitiro anonzi alcalation.
7. Kugadzirwa kweHeterocycclic Comprounds: Diethyl Mallonis inoshandiswa mune synthesis yeHeterocycclic Comprounds, izvo zvakakosha mumishonga yemushonga.
8. Kucherekedza uye zvinonhuwira: Nekuda kwekunhuhwirira kwayo, inogona kushandiswawo mune zvechikafu nezvinonhuwira.
Izvo zvinonyangadza mu chloroform, benzene uye imwe organic sol sol. Zvishoma zvishoma mumvura.
1. Chengetedza muchitoro chinotonhorera, chakaputirwa. Ramba kure nemoto uye kupisa masosi. Inofanira kuchengetwa zvakasiyana kubva kune oxidants, yakasimba alkalis, uye kuderedza vamiririri, uye kudzivirira kuchengetedza kwakasanganiswa. Yakarongedzwa neiyo yakakodzera mhando uye huwandu hwemidziyo yemoto. Nzvimbo yekuchengetera inofanira kuve yakashongedzerwa nemidziyo yekurapa ekurapa ekurapa uye zvinhu zvakakodzera zvekuchengetedza.
2. Chengetedza uye kutakura zvinoenderana nemirairo yemakemikari anopisa.
1. Mudziyo: Chengetedza dihtyl mallon mumudziyo wakasungwa kudzivirira kusvibiswa uye kubuda kwemvura. Shandisa midziyo yakagadzirwa negirazi kana purasitiki inoenderana.
2. Zvakanakisa, inofanira kuchengetwa pamhepo tembiricha kana mufiriji kana nguva refu yekuchengetedza ichidikanwa.
3. Inerer Gasi: Kana zvichikwanisika, chengetedza pasi pegasi kana nitrogen kana argon kuti uderedze kuratidzwa nemhepo uye mhepo, inogona kukonzera hydrolysis kana oxidation.

5. Kuchengetedza Kwekudzivirira: Tevedza nhungamiro dzese dzekuchengetedza nemirairo yekubata nekuchengetedza makemikari, kusanganisira iyo yakakodzera michina yekudzivirira (PPE) paunenge uchibata diethyl mallon.
1. Ngwarira kusangana nevehudhiyo, kuderedza vamiririri uye alkalis. Izvo zvigadzirwa zvemakemikari zvakakosheswa pane diethyl oxacolate. Sezvo iri nyore hydrolyzed yekugadzira mloni acid, iyo iri yakawanda acidic, inodiwa kudzivirira kubaya kwemapor kana kusangana neganda.
2. Ichi chigadzirwa chine kuderera kwepfuma, rat aral ld50> 1600mg / kg, asi ichave hydrolyzed mu acid mumuviri, dzivisa kusangana. Geza mushure mekusangana. Vashandisi vanofanirwa kupfeka magurovhosi eRabha.
1. Regulatory kutevedzera: Ita shuwa kuti iwe uteedzere nemirau yemunharaunda yemunharaunda, yenyika uye yenyika maererano nekufambisa kwemakemikari. Izvi zvinogona kusanganisira kunyora kwakakodzera, zvinyorwa uye kutevedzera zvine njodzi zvine hungwaru zvemidziyo.
2. Iyo mudziyo unofanirwa kunge wakaburitswa uye zvakagadzirwa nezvinhu zvisingaite nemakemikari. Ita shuwa kuti kurongedza kwakasimba zvakakwana kuti uwane kubata kwekufambisa panguva yekufambisa.
3 Ngwarira kuratidzwa nekunyanyisa kupisa, izvo zvinokanganisa kutendeka kwemakemikari.
4.
5. Kuchengetedza Kwemunhu (PPE): Ita shuwa kuti vashandi vanokonzera kufambisa malloned pfeka ppe, kusanganisira magurovhosi, uye zvipfeko zvekudzivirira kudzivirira ganda uye kutarisana nemeso.
6. Maitiro emergency: ane emergency maitiro munzvimbo mune iyo spill kana kubhururuka kunoitika panguva yekufambisa. Izvi zvinosanganisira kuve neyakagadziriswa kit nguva dzose uye kuona vashandi vanodzidziswa mumhinduro yekukurumidzira.
