beta-hydroxybutyras Natrii BHB CAS NO 150-83-4 BHB
Natrii 3-hydroxybutyras late in natura, sanguine humano et urina invenitur. Activitatem opticam ostendit et in statu puro crystallizari potest. Greges hydroxylici facile in aqua, aethanolo, aethere, et vapore sicco coniungi et dissolvi possunt. Propter praesentiam gregis polaris OH, aciditas eius k augetur, et facile cum alcoholibus vel acidis reagitur. Polymerum 3-hydroxybutyratis a microorganismis in condicionibus tam aerobicis quam anaerobicis decomponi potest, ita in materiis plasticis biodegradabilibus adhiberi potest, sed nulla productio industrialis magnae scalae in praesenti est.
