Malonic acid, yomwe imadziwikanso kuti malonic acid, ndi organic acid yokhala ndi mankhwala otchedwa HOOCCH2COOH, omwe amasungunuka m'madzi, ma alcohols, ethers, acetone ndi pyridine, ndipo amakhala ngati mchere wa calcium mu mizu ya beet ya shuga. Malonic acid ndi kristalo wopanda mtundu, wosungunuka, 135.6 ° C, amawola pa 140 ° C, kachulukidwe 1.619g / cm3 (16 ° C).
Ntchito:
(1) Amagwiritsidwa ntchito ngati intermediates mankhwala, amagwiritsidwanso ntchito zonunkhira, zomatira, zowonjezera utomoni, electroplating ndi kupukuta wothandizila, etc..
(2) Amagwiritsidwa ntchito ngati wothandizira, amagwiritsidwanso ntchito pokonzekera mchere wa barbiturate, etc.
(3) Malonic asidi ndi wapakatikati wa fungicide mpunga fungicide, komanso wapakatikati wa zomera kukula indocyanate.
(4) Malonic asidi ndi esters ake zimagwiritsa ntchito mafuta onunkhira, zomatira, utomoni zina, intermediates mankhwala, electroplating ndi kupukuta wothandizila kuphulika, wothandizila kuphulika, otentha kuwotcherera flux zina, etc. Mu makampani mankhwala ntchito kupanga luminal. , barbiturates, vitamini B1, vitamini B2, vitamini B6, phenyl pausticum, amino acid, etc. Malonic acid amagwiritsidwa ntchito ngati mankhwala opangira aluminiyamu ndipo alibe vuto la kuipitsa chifukwa madzi okha ndi carbon dioxide amapangidwa akatenthedwa ndi kuwonongeka. . Pachifukwa ichi, ili ndi mwayi waukulu kuposa mankhwala opangira asidi monga formic acid, omwe amagwiritsidwa ntchito kale.
(5) Malonic acid amagwiritsidwa ntchito ngati chowonjezera pakupanga mankhwala komanso ngati chopukutira cha electroplating.
