Isingeniso
I-Dimethylmalonic acid (eyaziwa nangokuthi i-succinic acid) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-dimethylmalonic acid:
Ikhwalithi:
- Ukubukeka: I-Dimethylmalonic acid ngokuvamile i-crystalline engenambala noma impushana emhlophe.
- Ukunyibilika: Kuncibilika kuzincibilikisi ezivamile ezifana namanzi, i-ethanol ne-ether.
Sebenzisa:
- Njengempahla yokusetshenziswa yezimboni: Ingasetshenziselwa ukuhlanganisa ama-polyester resins, ama-solvents, ama-coatings nama-glues.
Indlela:
- Indlela evamile yokulungiswa kwe-dimethylmalonic acid itholakala nge-hydroformylation ye-ethylene additive. Isinyathelo esiqondile siwukuba i-hydrogenate ethylene ene-formic acid yakhe i-glycolic acid, bese kuqhubeka ukusabela kwe-esterification phakathi kwe-glycolic acid ne-formic acid ukuze kutholwe umkhiqizo wokugcina we-dimethylmalonic acid.
Ulwazi Lokuphepha:
- I-Dimethylmalonic acid ayinabo ubuthi, kodwa kusafanele kuqashelwe ukulandela izinqubo zokusebenza eziphephile elabhorethri kanye nendawo yokukhiqiza.
- Vimbela ukuhogela uthuli noma ukuthinta isikhumba namehlo lapho uyisebenzisa, futhi gqoka izinto zokuzivikela ezifanele (isb., amagilavu nezibuko).
- Uma uthintana ngephutha, geza indawo ethintekile ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha uma kunesidingo.
