Gabatarwa
2-Methyl-2-pentenic acid, kuma aka sani da butenedic acid, wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga kaddarorin, amfani, hanyoyin shiri da bayanan aminci na 2-methyl-2-pentenoic acid:
inganci:
-2-Methyl-2-pentenoic acid ruwa ne mara launi zuwa kodadde ruwan rawaya mai wari irin na 'ya'yan itace.
-2-Methyl-2-pentenoic acid yana narkewa a cikin ruwa da abubuwan kaushi na halitta kamar su alcohols da ethers.
- Tsayayyen fili ne wanda baya kunnawa kai tsaye ko kuma ya tashi a yanayin zafi da matsi na al'ada.
Amfani:
- 2-Methyl-2-pentenoic acid ana amfani da shi da farko a cikin shirye-shiryen polymers masu girma kamar su na musamman, adhesives, da sealants.
- Yana da mahimmanci monomer na biyu wanda za'a iya shirya ta hanyar polymerization na butenic acid copolymers.
Hanya:
- 2-Methyl-2-pentenoic acid za a iya shirya ta acid-catalyzed ƙari na cyclohexene.
- Dimethyllithium da cyclohexene suna amsawa don samun 2-methyl-1-cyclohexenylmethyllithium, sa'an nan kuma hydrolyzed da acidified don samun 2-methyl-2-pentenoic acid.
Bayanin Tsaro:
- 2-Methyl-2-pentenoic acid wani abu ne mai ban haushi wanda zai iya cutar da fata da idanu, kuma ana buƙatar matakan kariya kamar sanya safar hannu da tabarau na kariya yayin amfani.
- Ba shi da kwanciyar hankali ga haske da yanayin zafi mai girma, kuma halayen polymerization na iya faruwa, don haka ya kamata a kauce wa tsawan lokaci mai tsawo ga hasken rana ko ajiya a yanayin zafi.
- Lokacin sarrafawa da adanawa, ya kamata a kiyaye shi daga kayan da za a iya ƙonewa da kuma abubuwan da ke haifar da oxidizing don hana haɗarin wuta ko fashewa.
