Applications NVP
NVP maxime adhibetur ad polyvinylpyrrolidone producendos, quae late in agris medicinae, cotidianae industriae chemicae et cibi adhibetur.
1. Late usus est in stibio, purgat, medicina, materia photosensitiva et aliis agris
2. Ad pilorum tas nes, pharmacopolium disinfectantes, etc.
Praeparatio processus phaeasonis N-ethylenae, cum sequentibus gradibus: 1. Catalystae dehydratae praeparationis catalystae dehydratae continent sulphatem argenti, sodium aluminii silicati, carbonis albi nigri, amproof, et multi- oxydi.Proportio est : 0.5 : 5: 3:5 : 10 ;Inter quas multi -oxides sunt quinque mixturae quinque oxidationis duo et oxydi, oxydi stagni, oxydi sex, dioxidi manganesi;Est mixtura oxidationis quinque dioxidi et oxydi, oxidationis quinque duo -钒 et oxydi stagni, oxidationis quinque duo, manganesi oxydi et dioxidi manganesi.Mixtura oxydationis septimae dioxidis est 0.2: 1: 2: 1. Gradus productio catalystorum dehydratorum sunt: misce sulphatem argenti, amproof, et oxydatum multi in proportione, adde volumen aquae decoctae I temporibus, compone pH. valorem acidi sulphurici et ammoniae aquae ad 6,5 ad 7, adde sodium silicinum et sodium siliconatum et pro proportionibus.Carbonum album est nigrum, calefactum et commotum ad solutionem uniformem faciendam;in aqua balnei suscitare et solutionem siccare condensare, 100-120° C ad 6 ad 8h siccare, deinde coquere pro 3 ad 5h ad 400~ 450 ° C. 2. Praeparatio N-hydroxyethylpylpylini (NHP) 1). Misce γ-butanol, unum ethanolum, et ammoniacum ratione 1.2: 1: 0.2, et reagit ad 0.5MPa et 40° C. Fac medium;2) Sievum hypotheticum addere 0.1WT% et 0.1WT% aetheris dihalationis dihalationis augere temperiem ad 180°C, ut eam per 12h in statu retento dehydratam faciat;quid describitur;quid memoratur?Cribrum hypotheticum est 10xchemical liber cribrum hypotheticum seu 13X cribrum hypotheticum.Haec methodus ut 10x cribra hypothetica eligatur;3) Decompressionis distillationis, vacuum est 0.095MPa, et colligit distillationem ebullientis punctum 210 ad 216° C. Pyrodorroni;3. Reactio siccitatis hydroxyetylpinoli N-hydroxyetylpinoli ad distillationis score consecuta in praeparatione N-hydroxyethylpinoli in vapore mixto gasi alkalini, gasorum acetylenarum mixto, et nitrogenium ad mixtionem materiae rudis gaseorum obtinendam.Mixta ratio est 1: 0.5: 0.1: 0.1;Fac mixturam materiae gasicæ rudis sub conditione reactoris lecti catalysti dehydrati ad temperiem 350 ° C, pressionem 0.01MPa et celeritatem gasorum 50-300H-1, et siccitatibus siccitatibus fixis. lectus reactor Catalysta calefacta ad 390 ° C. Post reactionem siccitatem ad stateram pervenit, productum cephalopicone N-ethylene (NVP) productum e lecto reactori fixum emittitur.Alcalini vapores sunt saltem unus ammoniaci, methylemine, dihamine, trothalmine et ethimine.Chromatographiam analysis gasi adhibe methodum, secundum γ-butthite ut vexillum internum, ethanolum ut menstrua, evolvit productum cheedone N-ethylene praeparatum hac methodo, NHP conversionis rate, NVP selectivity, NVP reditus computans, cuius periodus gasi phase Phase phase, cuius gas phase phase phase phase Phase, of which gas phase phase was chromatographic of test conditions: TCD detector, immaculata chalybs, poly acetic glycol tannite dilate fixing solution, nitrogen onustus, silicanerization 102 alba antithesis, gasification locus temperatus 280 C, TCD detector temperatus 165°C, columnas, columnas, columnas temperies 190°C;computata analysi chromatographiae gasi: NHP conversio rate 92,8%, NVP selectivity 91,5%, et NVP reditus 85,6%.
