Gabatarwa
Dimethylmalonic acid (kuma aka sani da succinic acid) wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga kaddarorin, amfani, hanyoyin shiri da bayanan aminci na dimethylmalonic acid:
inganci:
- Bayyanar: Dimethylmalonic acid gabaɗaya ba shi da launi crystalline ko fari foda.
- Solubility: Mai narkewa a cikin kaushi na gama gari kamar ruwa, ethanol da ether.
Amfani:
- A matsayin albarkatun kasa na masana'antu: Ana iya amfani dashi don haɗa resins na polyester, kaushi, sutura da manne.
Hanya:
- Hanyar gama gari don shirye-shiryen dimethylmalonic acid ana samun su ta hanyar hydroformylation na ƙari na ethylene. Takamammen mataki shine hydrogenate ethylene tare da formic acid don samar da glycolic acid, sannan a ci gaba da amsawar esterification tsakanin glycolic acid da formic acid don samun samfurin ƙarshe na dimethylmalonic acid.
Bayanin Tsaro:
- Dimethylmalonic acid ba mai guba bane, amma ya kamata a kula da bin hanyoyin aiki masu aminci a cikin dakin gwaje-gwaje da kuma wurin samarwa.
- Hana shakar ƙura ko tuntuɓar fata da idanu yayin amfani da ita, da sanya kayan kariya masu dacewa (misali, safar hannu da tabarau).
- Idan aka yi mu'amala ta bazata, a wanke wurin da abin ya shafa nan da nan da ruwa mai yawa sannan a nemi taimakon likita idan ya cancanta.
