Intangiriro
2-Methyl-2-acide pentenique, izwi kandi nka acide butenedic, ni ifumbire mvaruganda. Ibikurikira ni intangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya 2-methyl-2-pentenoic aside:
Ubwiza:
- 2-Methyl-2-pentenoic aside ni ibara ritagira ibara ryumuhondo wijimye kandi ufite impumuro nziza yimbuto.
- 2-Methyl-2-pentenoic aside irashonga mumazi hamwe numuti wa organic nka alcool na ethers.
- Ni uruganda ruhamye rudahita rwaka cyangwa ngo ruturike ku bushyuhe busanzwe hamwe n’umuvuduko.
Koresha:
- 2-Methyl-2-pentenoic aside ikoreshwa cyane cyane mugutegura polymers ikora cyane nka coatings yihariye, ibifatika, hamwe na kashe.
- Nibyingenzi byingenzi bya monomer bishobora gutegurwa na polymerisation ya butenic aside copolymers.
Uburyo:
- 2-Methyl-2-pentenoic aside irashobora gutegurwa hiyongereyeho aside-catisale yongeyeho cyclohexene.
- Dimethyllithium na cyclohexene barabyakira kugirango babone 2-methyl-1-cyclohexenylmethyllithium, hanyuma hydrolyzed na acide kugirango babone aside 2-methyl-2-pentenoic.
Amakuru yumutekano:
- 2-Methyl-2-pentenoic aside ni ibintu bitera uburakari bishobora kurakaza uruhu n'amaso, kandi harakenewe ingamba zikenewe nko kwambara uturindantoki two gukingira hamwe n'amadarubindi mu gihe cyo kubikoresha.
- Ntabwo bihindagurika kumucyo nubushyuhe bwinshi, kandi reaction ya polymerisiyasi irashobora kubaho, bityo rero hagomba kwirindwa kumara igihe kinini kumurasire yizuba cyangwa kubika ubushyuhe bwinshi.
- Mugihe cyo gutunganya no kubika, bigomba kubikwa kure yumuriro ugurumana hamwe na okiside kugirango birinde ingaruka zumuriro cyangwa guturika.
- Iyo ukoresheje aside 2-methyl-2-pentenoic, protocole ikwiye yubushakashatsi hamwe nubuyobozi bukora neza. Mugihe habaye impanuka, ingamba zihutirwa zigomba guhita zifatwa kandi hagomba gushakishwa ubufasha bwubuvuzi bwumwuga.
