Phenylhydrazine nyob rau hauv Fischer indole synthesis tsim indoles. Hauv qhov tshuaj tiv thaiv no ib molecule ntawm qabzib reacts nrog ob lub molecules ntawm phenyl hydrazine los tsim glucosazone. Lus Cim - Glucosazone yog ib qho piv txwv ntawm osazone.
Glucosazone melting point yog dab tsi?
208 ° C melting point. Decomposition kub ntawm 213 ° C, polarimetry �?-0.35 -0.62 (24, c=2, pyridine thiab ethanol mixed solvents).
Glucosazone yog dab tsi?
1: osazone ntawm qabzib, mannose, lossis fructose. 2: Glucose phenylosazone.
Yuav ua li cas thaum cov piam thaj raug kho nrog phenylhydrazine?
Ceeb toom: Cov tshuaj tiv thaiv ntawm cov piam thaj nrog phenylhydrazine muab cov piam thaj phenylhydrazonewhereas cov tshuaj tiv thaiv ntawm cov piam thaj nrog ntau tshaj phenylhydrazine muab osazone. Cov suab thaj uas muaj dawb aldehyde lossis ketone pawg yog hu ua txo cov suab thaj.
Puas phenylhydrazine hnov qab qabzib?
Ib yam tshuaj tiv thaiv uas qhia txog kev tsim ntawm osazone. D-glucose reacts nrog phenylhydrazine muab glucosazone. Tib yam khoom yog tau los ntawm fructose thiab mannose.
