Pyridine cas 110-86-1 mea hoʻolako hale hana waiwai

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 nitratation, 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 hydrogen o pyridine me ka hydrogen kaumaha.
