اصطناع مركبات فوسفورية عضوية تملك الجسرP(S)NHP(O)- - ودراسة تأثيرها على استخلاص أيون النيكل من محلول الكبريتات بواسطة طريقة الاستخلاص السائل - السائل
Abstract
حُضر المركبان اللذان يملكان الصيغة العامة التالية : (RO)2- PS- NH- PO-(OPh)2 C6H4 , Ph )- -CH3 o R= ( التي تدعى µ - إيميدو تيو ثنائي حمض الفوسفور تترا أستر, من أجل الفنيل يصبح µ - إيميدو تيو ثنائي حمض الفوسفور تترا فنيل أستر ,يأخذ الاختصار TPhSO , يدعى المركب الثاني µ - إيميدو تيو ثنائي حمض الفوسفور ثنائي فنيل استر ثنائي أورتو كريزول , يأخذ الاختصار (DiPhDio- Kr(SO , تكون هذه المركبات حموض برونستد وتأخذ الرمز HA , استخدمت هذه المركبات كمواد استخلاص في طريقة الاستخلاص
السائل - السائل . إذ حُددت بعض الخواص الفيزيائية والكيميائية لهما .ودُرس توزع أيون النيكل بين وسط محلول الكبريتات المائية (0.5M) ووسط الاكزالين الحاوي على تراكيز مختلفة من المركبين السابقين . قيمت معلومات التوزع رقمياً وبيانياً , أظهرت النتائج أن الجزئيات المتشكلة في الطور العضوي تملك الصيغة NiA2 .
Two organo-phosphoric compounds having following general form (RO)2PS-NH-PO(OR)2 were synthesized, which is called µ- imido thiodiphosphoric acid tetra ester ,
R= (o-CH3-C6H4 or Ph) , for R=Ph become the name of compound µ- imido thio di phosphoric acid tetra phenyl ester . it takes the abbreviation TPhSO and for R= (o-CH3-C6H4 ) become the name µ- imido thio di phosphoric acid di phenyl ester di ortho cresol , it takes the abbreviation DiPh Dio-Kr(SO).These compounds are Bronsted acids and takes the abbreviation HA . They used as extractants in liquid-liquid extraction Method,Where was identified some of the physical and chemical properties for them and was Studied the distribution of nickel ion between the water sulfate solution (0.5M) and medium xylene containing different concentrations of the former compounds. the distribution data have been analyzed both the graphically and numerically ,the results have shown that the species extracted into the organic phase have the composition NiA2 .
