Paracetamol yog soluble hauv cawv , but cov solubility txo qis nrog qhov nce ntawm qhov ntev ntawm cov saw hlau carbon hauv n- cawv homologous series ( methanol rau 1-octanol). Cov solubility ntawm tshuaj paracetamol nyob rau hauv dej qis dua tshaj nyob rau hauv lwm cov polar solvents xws li cov cawv.
Ntawm no, puas yog paracetamol lipid lossis dej soluble?
PARACETAMOL (acetaminophen, N-acetyl-p-amino-phenol, 4-hydroxyacetanilide) yog qhov nruab nrab dej - thiab lipid - soluble tsis muaj zog organic acid. Nws muaj pKa tus nqi ntawm 9.5 thiab yog li ntawd feem ntau koom ua ke dhau ntawm lub cev ntau yam ntawm pH.
Tom qab ntawd, lo lus nug yog, vim li cas paracetamol yaj hauv propanone?

Paracetamol Raws li lub npe nthuav tawm muaj lub nplhaib uas muaj ntxhiab, phenol kom meej. Qhov no muaj OH-pab pawg, ua tsaug rau pawg ua haujlwm no paracetamol yog hygroscopic, uas yog hais tias nws khi dej , ntau heev uas cov khoom no tsis tuaj yeem daws hauv dej.
Puas yog paracetamol soluble hauv acetone?
Paracetamol yog ntau dua soluble hauv ethanol dua li ethanediol. Cov solubility kuj txo qis nrog qhov nce ntawm qhov ntev ntawm cov saw hlau rau cov ketones ( acetone , 2-butanone, thiab 4-methyl-2-pentanone). Cov solubility ntawm PA hauv dej tsawg dua li lwm cov kuab tshuaj hnyav xws li cawv.
