Incazelo Yomkhiqizo:
I-Malonic acid, eyaziwa nangokuthi i-malonic acid, iyi-asidi ephilayo enefomula yamakhemikhali ethi HOOCCH2COOH, encibilika emanzini, otshwaleni, ethers, e-acetone kanye ne-pyridine, futhi ekhona njengosawoti we-calcium ezimpandeni zebhitrudi likashukela. I-Malonic acid iyikristalu engenambala engenambala, indawo encibilikayo engu-135.6°C, ibola ku-140°C, ukuminyana i-1.619g/cm3 (16°C).
Isicelo:
(1) Ikakhulukazi esetshenziswa njengezithameli zemithi, futhi ezisetshenziswa izinongo, izinto ezinamathelayo, izithasiselo ze-resin, i-electroplating kanye nama-agent wokupholisha, njll.
(2) Isetshenziswe njenge-ejenti eyinkimbinkimbi, iphinde isetshenziswe ekulungiseleleni usawoti we-barbiturate, njll.
(3) I-Malonic acid iyisibulali sikhunta serayisi esibulala isikhunta, futhi siphakathi nendawo yesilawuli sokukhula kwezitshalo i-indocyanate.
(4) I-Malonic acid kanye nama-esters ayo asetshenziswa ikakhulukazi kumakha, izinto zokunamathisela, izithasiselo ze-resin, izithasiselo zemithi, ama-electroplating kanye nama-agent acwebezelayo, ama-ejenti okulawula ukuqhuma, izithasiselo ze-welding flux ezishisayo, njll. Embonini yezemithi isetshenziswa ekukhiqizeni ukukhanya. , ama-barbiturates, uvithamini B1, uvithamini B2, uvithamini B6, i-phenyl pausticum, ama-amino acid, njll. I-Malonic acid isetshenziswa njenge-ejenti yokwelapha engaphezulu kwe-aluminium futhi ayinazo izinkinga zokungcola njengoba kukhiqizwa amanzi ne-carbon dioxide kuphela lapho ishiswa futhi ibola. . Kulokhu, kunenzuzo enkulu kuma-ejenti okwelapha asekelwe ku-asidi njenge-formic acid, ayesetshenziswa esikhathini esidlule.
(5) I-Malonic acid isetshenziswa njengesengezo sokucwecwa ngamakhemikhali nanjenge-ejenti yokupholisha i-electroplating.
