Chiyambi chachidule
2-Methyl-2-pentenal imadziwikanso kuti prenal kapena hexenal. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha pawiri:
Ubwino:
2-Methyl-2-pentenal ndi madzi opanda mtundu okhala ndi fungo lachilendo. Ndi madzi omwe sasungunuka m'madzi ndipo amasungunuka m'madzi ambiri osungunulira. Pa kutentha kwa chipinda, imakhala ndi mphamvu yotsika ya nthunzi.
Gwiritsani ntchito:
2-Methyl-2-pentenal ili ndi ntchito zambiri zamafakitale. Itha kugwiritsidwanso ntchito ngati mphira wopangira mphira, mphira antioxidant, zosungunulira utomoni, etc.
Njira:
Kukonzekera kwa 2-methyl-2-pentenal nthawi zambiri kumapezeka ndi machitidwe a isoprene ndi formaldehyde. Masitepe enieni amakhala motere: pamaso pa chothandizira choyenera, isoprene ndi formaldehyde zimawonjezeredwa ku reactor mu gawo linalake ndikusungidwa pa kutentha koyenera ndi kupanikizika. Zomwe zachitika kwa nthawi yayitali, 2-methyl-2-pentenal yoyeretsedwa imatha kupezeka kudzera munjira monga kuchotsa, kutsuka madzi, ndi distillation.
Zambiri Zachitetezo:
2-Methyl-2-pentenal ndi mankhwala owopsa omwe amatha kukhumudwitsa maso, khungu, ndi kupuma kwapang'onopang'ono. Valani zida zodzitetezera zoyenera mukamagwira ntchito ndipo pewani kukhudzana mwachindunji momwe mungathere. Imakhalanso madzi oyaka moto ndipo iyenera kutetezedwa kuti isagwirizane ndi kutentha kwakukulu, moto wotseguka ndi oxidizing agents. Ngati kutayikira mwangozi, njira zoyenera ziyenera kuchitidwa mwamsanga kuti ziyeretsedwe ndi kutaya.
