Mawu Oyamba
2-Methyl-2-pentenic acid, yomwe imadziwikanso kuti butedic acid, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2-methyl-2-pentenoic acid:
Ubwino:
- 2-Methyl-2-pentenoic acid ndi madzi achikasu otumbululuka komanso onunkhira ngati zipatso.
- 2-Methyl-2-pentenoic acid imasungunuka m'madzi ndi zosungunulira organic monga ma alcohols ndi ethers.
- Ndi gulu lokhazikika lomwe silimangoyatsira kapena kudziphulitsa pa kutentha ndi kukanikiza wamba.
Gwiritsani ntchito:
- 2-Methyl-2-pentenoic acid amagwiritsidwa ntchito makamaka pokonza ma polima apamwamba kwambiri monga zokutira zapadera, zomatira, ndi zosindikizira.
- Ndi imodzi yofunika yachiwiri yomwe imatha kukonzedwa ndi polymerization ya butenic acid copolymers.
Njira:
- 2-Methyl-2-pentenoic acid ikhoza kukonzedwa ndi asidi-catalyzed kuwonjezera kwa cyclohexene.
- Dimethyllithium ndi cyclohexene amachitidwa kuti apeze 2-methyl-1-cyclohexenylmethyllithium, ndiyeno hydrolyzed ndi acidified kuti apeze 2-methyl-2-pentenoic acid.
Zambiri Zachitetezo:
- 2-Methyl-2-pentenoic acid ndi chinthu chokwiyitsa chomwe chingakhale chokwiyitsa khungu ndi maso, ndipo kusamala koyenera monga kuvala magolovesi oteteza ndi magalasi amafunikira pakugwiritsa ntchito.
- Imakhala yosasunthika pakuwala komanso kutentha kwambiri, ndipo ma polymerization amatha kuchitika, chifukwa chake kuyenera kupewedwa nthawi yayitali ndi kuwala kwa dzuwa kapena kusungidwa kutentha kwambiri.
- Pogwira ndi kusungirako, ziyenera kusungidwa kutali ndi zinthu zoyaka moto ndi oxidizing kuti ateteze kuopsa kwa moto kapena kuphulika.
- Pogwira 2-methyl-2-pentenoic acid, ndondomeko yoyenera yoyesera ndi ndondomeko zoyendetsera ntchito ziyenera kutsatiridwa. Pakachitika ngozi, njira zoyenera zadzidzidzi ziyenera kuchitidwa mwamsanga ndipo thandizo lachipatala la akatswiri liyenera kufunidwa mwamsanga.
