Intshayelelo
(1H)-enye (1H)-enye) i-organic compound kunye ne-chemical formula C6H7NO2. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
(1H) -enye yikristale emhlophe eqinileyo, engenavumba. Izinzile kumaqondo obushushu aqhelekileyo, kodwa inokubola kumaqondo aphezulu. Indawo yayo yokunyibilika iphakathi kwe-140-144 degrees Celsius.
Sebenzisa:
(1H) -enye inoluhlu olubanzi lwezicelo kwi-organic synthesis. Ingasetyenziselwa njengendawo ephakathi kwi-organic synthesis ye-synthesis yezinye iikhompawundi, ezifana namayeza, idayi kunye nezibulali-zinambuzane. Ukongeza, inokuphinda isetyenziswe njengesixhobo sokudibanisa isinyithi ukwenzela ukuphendulwa kwe-catalytic.
Indlela yokulungiselela:
Kukho iindlela ezimbini eziphambili zokulungiselela (1H) -enye. Enye kukuqaliswa kweqela le-hydroxyl kunye neqela le-methyl kwiringi ye-pyridine nge-alkylation yeqela le-hydroxyl ye-picoline. Enye indlela kukwenza i-hydroxyl alkylation reaction kwiringi yepyridine ukwazisa iqela le-hydroxyl kunye neqela le-methyl. Indlela ethile yokulungiselela inokukhethwa ngokweemfuno kunye neemeko ezithile.
Ulwazi ngoKhuseleko:
(1H) -enye ayinatyhefu kodwa kufuneka iphathwe ngononophelo. Ngethuba lokusebenza, kufuneka kuthathelwe ingqalelo ukuphepha ukudibanisa ngokuthe ngqo kwesikhumba kunye namehlo, kunye nokuqinisekisa ukuba umsebenzi ukwindawo yomoya. Ukuba ukudibana ngengozi, kufuneka kuhlanjululwe ngokukhawuleza ngamanzi kunye nonyango lwangexesha lonyango. Ukongezelela, kufuneka igcinwe kwisitya esivaliweyo, kude nomlilo kunye ne-oxidizing agents.
Nceda uqaphele ukuba xa usebenzisa kwaye uphatha nayiphi na ikhemikhali, kufuneka ulandele iinkqubo zebhubhoratri ezichanekileyo, kwaye ubhekiselele kwiphepha ledatha yokhuseleko (SDS) yento kunye nesikhokelo samaziko aqeqeshiweyo.
