Kupanga Sodium Hydrosulfide kwiinda mu Sodium Ethoxide a H2S
Kulibambila kwiinda mukubelesya Sodium Ethoxide a Dry Hydrogen Sulfide
Kubamba zibelesyo:
Ifulasiki lya 150 mL lijisi ntobo yakumbali lilabikkwa 20 mL ya bupya bwakasanzyigwa Ethanol iitakwe maanzi lubo 2 g yazibeela zya sodium zisalala (zitakwe zibeela zya oxide).
Ifulasiki ilibikkidwe a reflux condenser antoomwe a tube yakuyuminizya, mpawo bbazu lyamumbali lyakajalwa kwakaindi kaniini.
Nikwakainda sodium ethoxide niyakatalika kupanga, chimwi 40 mL ya ethanol iitakwe maanzi ilayungizigwa muzibeela kusikila mane yanyonyooka.
Kuchita a Dry H2S:
Igilazi tuyubi lilabikkwa kwiinda mumbali aamusamu, mpawo muya uuyumu wa H2S ulabumbuluka mukati (bona kuti kuli busena butakwe muya kutegwa muya utanjili).
Musamu ooyu ulazula a H₂S, mpawo ulasefwa kuti ugwisye zintu zyoonse.
Ikusefa kulabikkwa mufulasi lyamukoko liyumu, mpawo 50 mL ya ether iizulide yakayungizigwa, mpawo mpawo yakapa kuti NaHS isalala.
I ether iimbi (~110 mL yoonse) ilabikkwa muzibeela kusikila mane kutabi mvwula imbi.
Ikuzwa ansi kulafwambaana kusefwa, kusanzyigwa ziindi zili 2-3 a absolute ether, mpawo kuyuminizyigwa mu vacuum.
Chipangwa chili kabotu loko. Kuti kube kusalala kupati, kubambulula kuzwa ku ethanol/ether kulakonzya kuchitwa.
