Pyridine 110-86-1 kumu kūʻai hana

1. ʻAʻohe decomposition ma lalo o ka mahana maʻamau a me ke kaomi.E pāpā i ka hoʻopili ʻana me nā ʻakika, nā mea hoʻomake ikaika, a me ka chloroform.ʻAʻole pono e hoʻohana ʻia nā ipu keleawe.Hōʻalo i ka mālama ʻana me nā mea hoʻomake ikaika e like me ka peroxides a me ka waikawa nitric.

2. He paʻa ka Pyridine i nā mea hoʻoheheʻe a ʻaʻole i hoʻoheheʻe ʻia e ka nitric acid, chromium oxide, potassium permanganate, a me nā mea ʻē aʻe, no laila hiki ke hoʻohana ʻia e like me ka solvent i ka hopena oxidation me ka permanganate.ʻO ke kuleana o ka hydrogen peroxide a i ʻole ka peracid e lilo i N-oxide (C5H5NO).

3. He mea paʻakikī i ka pyridine ke komo i ka hopena electrophilic substitution, ʻaʻole hoʻi e kū mai ka hopena Friedel Crafts.I ka wā o ka nitration, pono ke kiʻekiʻe o 300 ° C no ka loaʻa ʻana o 3-nitropyridine, a haʻahaʻa ka hua.Akā hiki ke hoʻololi i ka nucleophilic substitution reaction.No ka laʻana, me ka sodium amide e hana i ka 2-aminopyridine.Ke hoʻohana ʻia ka platinum a i ʻole ka alkali ma ke ʻano he catalyst e launa pū me ka wai kaumaha, hiki ke hoʻololi ʻia ka lua o ka hydrogen o pyridine me ka hydrogen kaumaha.
