Hydroxypropyl methylcellulosum, etiam hypromellosum et cellulosum hydroxypropyl methyl notum, fit ex xylino valde puro celluloso et specialiter aethereis sub conditionibus alcalini.
differentia;
notis
Hydroxypropyl methylcellulosum: album vel album fibrarum instar pulveris vel granuli, variarum generum non-ionicarum in mixtione cellulosa pertinentium, hoc productum est semi-syntheticum, polymerum viscoelasticum otiosum.
Hydroxyethyl cellulosum est album vel flavum, odoriferum, fibra non-toxica, vel pulveris solidi, materia rudis alcali cellulosa et ethylene oxydi etherificationis, quae aether cellulosa non-ionica solubilis est.
Usus differt
In pingendo industria, hydroxypropyl methylcellulosum bonam habet solubilitatem in aqua vel menstrua organica sicut densior, dissipator et stabilior.Polyvinyl chloride ponitur pro remotore fuco ad polymerizationem suspensionis ad chloridem parandam, quae late in corio, charta producta, fructu et conservatione vegetabili adhibetur, textilia et aliae industriae.
Hydroxypropyl methylcellulosum: fere insolubile in ethanolo absoluto, aethere, acetono;solutum in solutione colloidali pellucida vel turbida in aqua frigida, late adhibita in coatingiis, atramentis, fibris, tingendis, cinematographicis, cosmeticis, pesticidis, mineralibus processus productus, recuperatio olei et industriae pharmaceuticae.
diversis solubility
Hydroxypropyl methylcellulosum: fere insolubile in ethanolo absoluto, aethere, acetono;solutum in aqua frigida diluta vel leviter nubilum solutione colloidali.
Hydroxyethyl cellulosum (HEC): Solutiones in diversis viscositatis iugis praeparare potest et bonas proprietates salis dissolventes electrolytici habet.
