Mayelana ne-Malonic acid CAS 141-82-2
I-Malonic acidiyikristalu Emhlophe, Incibilika kalula emanzini, incibilika ku-ethanol ne-ether.
Isicelo
Ukusetshenziswa 1:I-Malonic acid CAS 141-82-2ikakhulukazi esetshenziswa njengezinqamuleli zemithi, kodwa futhi nezinongo, izinto zokunamathisela, izithasiselo ze-resin, ama-ejenti wokupholisha nge-electroplating, njll.
Ukusetshenziswa 2:I-Malonic acidisetshenziswa njenge-ejenti eyinkimbinkimbi futhi nasekulungiseni usawoti we-barbiturate
Ukusetshenziswa 3:I-Malonic acidiyisibulali sikhunta i-Daowenling, futhi iphinde ibe maphakathi nesilawuli sokukhula kwezitshalo i-indomethacin.
Ukusetshenziswa 4:I-Malonic acidfuthi ama-esters ayo asetshenziswa kakhulu kuzinongo, izinto zokunamathisela, izithasiselo ze-resin, izixhumi zemithi, ama-ejenti wokupholisha i-electroplating, ama-ejenti okulawula ukuqhuma, izithasiselo ezishisayo ze-welding flux, njll.
Ukusetshenziswa 5: Embonini yezemithi,I-Malonic acid CAS 141-82-2isetshenziselwa ukukhiqiza i-Rumina, i-Barbital, i-Vitamin B1, i-Vitamin B2, i-Vitamin B6, i-Phenyl Phenylbutazone, i-Amino Acids, njll.
Ukusetshenziswa 6:I-Malonic acidisetshenziswa njenge-ejenti yokwelapha engaphezulu kwe-aluminium. Ngenxa yokuthi amanzi ne-carbon dioxide kuphela akhiqizwa ngesikhathi sokushisisa nokubola, ayikho inkinga yokungcola.
Kulokhu, kunezinzuzo eziphawulekayo uma kuqhathaniswa nama-ejenti okwelapha asekelwe ku-asidi afana ne-formic acid eyayisetshenziswa esikhathini esidlule.
Izimo Zokugcina
1. Ivalwe futhi igcinwe.
2. Sebenzisa izikhwama ezilukiweyo ezifakwe ulayini wepulasitiki ukuze upakishwe, ezinesisindo esingama-25kg. Gcina futhi uthuthe ngokwemithetho ejwayelekile yamakhemikhali.
Ukuzinza
1. Izinzile ekamelweni lokushisa nokucindezela.
Izinto ezingavunyelwe: i-alkali, i-oxidant, i-ejenti yokunciphisa.
2. Ubuthi obuphansi. Inemiphumela ecasulayo esikhumbeni kanye nolwelwesi lwamafinyila, kodwa hhayi kakhulu njenge-oxalic acid. I-LD50 yomlomo yamagundane ingu-1.54g/kg. Ngokuvamile, asikho isivikelo esikhethekile esidingekayo ukuze kukhiqizwe i-Malonic acid, kodwa i-cyanoacetic acid ne-Sodium cyanide zombili ziwushevu obuqinile. Ngakho-ke, ukunakekelwa okukhethekile kufanele kuthathwe lapho kusingathwa izinhlanganisela eziqukethe amaqembu e-cyano. Impahla yokulwa nobuthi kufanele igqokwe futhi kwenziwe izinyathelo zokuphepha ezifanele.
Izinyathelo zosizo lokuqala
Ukuxhumana kwesikhumba:Susa izingubo ezingcolile bese ugeza ngamanzi agelezayo. Uma kukhona ukusha, kuphathe njengokusha kwe-asidi.
Ukuthintana kwamehlo:Ngokushesha vula amajwabu amehlo angaphezulu nangaphansi bese ugeza ngamanzi agobhozayo imizuzu engu-15. Funa usizo lwezokwelapha.
Ukuhogela:Susa ngokushesha endaweni yesehlakalo uye endaweni enomoya omusha. Nikeza umoya-mpilo lapho ukuphefumula kunzima. Lapho ukuphefumula kuyeka, yenza ngokushesha ukuphefumula okwenziwa. Funa usizo lwezokwelapha.
Ukungenisa:Labo abayithatha ngephutha kufanele baphuze ubisi noma amaqanda amhlophe. Funa usizo lwezokwelapha.
Xhumana nathi
Uma ufunaI-Malonic acid CAS 141-82-2, Umphakeli wokukhiqizaI-Malonic acid,I-Malonic acidngentengo yefekthri.
Siyakwamukela ukuxhumana nathi nganoma yisiphi isikhathi, sizokuthumela imininingwane enemininingwane eminingi kanye nentengo engcono kakhulu yereferensi yakho.
