APAKAH MAKSUD NITRATION dalam CORSICA?
Nitrasi
Nitrasi adalah kelas umum proses kimia untuk pengenalan kumpulan nitro ke dalam sebatian kimia organik. Lebih longgar istilah juga digunakan secara tidak betul untuk proses yang berbeza membentuk ester nitrat antara alkohol dan asid nitrik, seperti yang berlaku dalam sintesis nitrogliserin. Perbezaan antara struktur yang terhasil dari sebatian nitro dan nitrat adalah bahawa atom nitrogen dalam sebatian nitro langsung terikat kepada atom bukan oksigen, biasanya karbon atau atom nitrogen lain, sedangkan dalam ester nitrat, juga disebut nitrat organik, nitrogen terikat kepada atom oksigen yang pada gilirannya biasanya terikat kepada atom karbon. Terdapat banyak aplikasi perindustrian utama nitrasi dalam pengertian yang ketat; yang paling penting dengan isipadu adalah untuk pengeluaran sebatian Nitroaromatik seperti nitrobenzene. Reaksi pengasingan terutamanya digunakan untuk pengeluaran bahan letupan, contohnya penukaran guanidine kepada nitroguanidine dan penukaran toluena kepada trinitrotoluene. Walau bagaimanapun, ia amat penting sebagai perantaraan kimia dan prekursor. Berjuta-juta tan nitroaromatik dihasilkan setiap tahun.
Definisi nitration dalam kamus Corsica
Definisi pertama nitrasi dalam kamus adalah tindakan atau proses merawat dengan asid nitrik atau nitrat. Takrifan lain nitrasi adalah tindakan atau proses menukar menjadi nitrat. Nitrasi juga merupakan tindakan atau proses yang menyebabkan untuk menjalani proses kimia di mana kumpulan nitro diperkenalkan ke dalam molekul.
