UMGAQO-NKQUBO WOKUGQIBELA WOKUZIPHATHA KWE-SULPHIC SulSul Sullic kwigalikhi yehyddy e-china

Lo mgangatho ulingana nombutho wamazwe aphesheya wokubekwa emgangathweni (i-ISO) 5567-1982 "Ukuzimisela kwe-sulfich ye-ortic suplic kwigalikhi ye-Declic".

Isishwankathelo sendlela

Isampulu ifakwe emanzini, e-Ethanol yongezwa, i-witganosul ye-organosur ichithwe, kwaye i-right-ring ephakathi ye-Nitric Acid inesibi-mali ityalwe kwisisombululo sesilivere yesilivere.

Iirejista ezi-2

2.1 I-Nitric Acid (i-Gravives ekhethekileyo 1.42)
2.2 I-Ethanol 95% (v / v)
2.3 Iparafini ye-ratin
2.4 Nitric Acid 10% (v / v)
2.5 I-Ammonium hydroxide 10% (v / v)
I-2.6 0.1000Mol / l isilivere yesilivere, ukulungiselela kunye nendlela yokulinganisa ngokwe-GB 601-1977 "Indlela yokulungiselela iShemical" indlela yokulungiselela isimo sezulu.
I-2.7 0.1000Mol / L Ammol Stoocyastate esemgangathweni, ubunzima be-Ammonium Thiocyanate 8G inyibilikisiwe kumanzi e-1l. Isalathiso soLingazo I-GB 601
I-2.8 ye-Ferric Ammonium yesalathiso sesalamane isisombululo, isisombululo esipheleleyo.

Isixhobo esi-3

Ngexesha lokuqulunqwa, ngakumbi izixhobo zokuhambisa izixhobo zokudibanisa kufuneka zithintelwe unxibelelwano ngobhedu okanye iimveliso zerabha, izixhobo zokuhlukanisa zinonxibelelwano lweglasi yomlomo.
3.1 Izixhobo zokuSebenza (jonga umzobo) yi-flask ye-Flask engama-250ML, ekwaziyo ukumiswa kunye ne-gooseneck elw uqhagamshelo oluthe ngqo okanye iglasi ye-goose computer okanye iglasi ye-goute.
I-3.2 250 ml i-flarks ye-flassicals, ikwazi ukusetyenziswa ngokunxulumene ne-countenser.
3.3 Iqondo lokushisa rhoqo lamanzi, liyakwazi ukulawula ubushushu ukuya kwi-37 ± 1 ° C.
I-3.4 G2 okanye G3 funnel.
I-3.5 vacuum impompo okanye impompo yamanzi.
3.6 Iphepha le-PH PLINTIVION, ekwaziyo ukubonakalisa i-PH = 7 ± 0.1. Iyunithi yokulinganisa i-sulfur yesalfure.

Iinkqubo ezi-4

4.1 Isimo sesampulu
Iiflegi zeGrisile zenziwe zangathi zifakwe iiyunifomu kwaye emva koko isampulu ye-Granules, iGranurad Granules kunye ne-Galic Powder ibekwe ngqo.
4.2 Ubungakanani besampulu
Ubunzima malunga ne-10G isampulu, ichanekile kwi-0.01G.
4.3 Ukuzimisela
4.3.1 Ukuhamba
Beka isampulu ye-flask (3.1) nge-100ml ye-40ml ye-40 ° C, unqamle iflegi yeglasi yeglasi (3.3) kwiqondo lokuhlaselwa kwamanzi angama-37 ° 1 ° C ukuba le-2h .
4.3.2 Ukudibana
Emva kongeza i-20ml ye-ethanol (2.2) kunye ne-2ml ye-paraffini ye-raffini (2.1), qhagamshela i-flask (Jonga umfanekiso), kwaye wongeze i-10ml ye-Ammonium hydrox ( 3.2) Ukuze imbonakalo esezantsi ye-condenser iphantsi kwi-Amomoium hydroxide.
Fudumeza iFlask (3.1) ukuyeka ukukhululwa emva kwe-60 ml yesikali, hlamba ukhuphelo ngamanzi, kwaye uqokelele ukuhlanjwa kweflask.
Iqondo lokushisa kufuneka lilawulwe ngexesha lokuphanga ukunqanda ukuchitheka kweebhubhu zegesi kunye nokuvumela inqanaba elifanelekileyo lokufumana izidanga.
4.3.3 Isibonelelo
Nxibelelanisa i-distrillate (a) kwi-Flask ye-Diric ene-Nitric Acid (2.4) kwaye uzinze i-PH ngo-7 ± 0.1 ngokuchanekileyo uyongeza i-20,00 ml yesisombululo esisezantsi se-witrate yesilivere (2.6) ukuya kwi-distillate (a) kwaye uyitshise kwindawo yokuhlambela amanzi kwi-1 h. I-distrillate (a) ipholile kubushushu begumbi kwaye icotshwe ngokupeyitha kunye nempompo yeglasi okanye impompo yamanzi (i-3.5) kunye ne-pumputer ihlanjwe ngamanzi amashushu ama-4 kunye nokuhlanjwa (B ) baqokelelwa. Yongeza i-5 ml ye-Nitric Acid (2.1) kunye namaconsi ambalwa e-Fermic Aramoni yesalathisi (2.8) kwisisombululo se-Fillic Smorication (2.8) kwisisombululo se-0.1000 mol / l) isisombululo esisezantsi (2.7) kude kube sisisombululo Brown-bod kwaye uyigcine i-0.5 min.

Ukubalwa kweziphumo zohlalutyo

5.1 Indlela yokubala
Umxholo we-volindarhing organoulfur kwigalikhi ye-Deecling eveliswe njengepesenti ye-Arlydar inikezwe yile fomyulDur inikezwe yile fomyula ye-Arlydar inikezwe yile fomyula: MCVCx100057.0) 20 (21)
Phi: x -ipesenti yomxholo we-volatile ye-organosul quages ​​kwigalikhi yehydddy,%;
I-C1 -Ukugxininiswa kweSisombululo seSilivere (2.6), mol / l;
I-C2 -Ukugxininiswa kwe-Ammonium ye-Ammonium ye-Ammonium Thinese (2.7), mol / l;
V - Ivolumu ye-Ammoyium ye-Ammonium ye-tioclosate ityiwa, ml;
I-0.057-I-GRAMs ye-SURMFUR SULPUR [(Ch2CH = ch2) i-2S] ilingana ne-1.00 ml yesisombululo esisezantsi se-pitrate ye-CLITY SITRE / 1.000 Mol / L;
m - ubunzima be-timemen g. Iziphumo ezifunyenweyo ziya kubonakaliswa kwiindawo ezimbini zokugqibela.
5.2 Ukuchaneka kwendlela
Kwi-operator enye, umahluko phakathi kweziphumo ezimbini ezilandelelanayo akufuneki udlule kwiipesenti ezi-5 zexabiso labo elichanekileyo, ngenye indlela uphinda umiselo.
5.3 Ingxelo yovavanyo
Thatha intsingiselo ye-arithmetic yezigqibo ezimbini njengesiphumo.
