- Introductio Ob restrictionem energiae domesticae petrolei et technologiae expolitio, oleum productorum regularium in foro productorum in brevi copia copiae sunt, quae magnum numerum productorum olei mixti mercatum inundant. Gasolina regularis mixta maxime miscetur cum naphtha aromatico mixto (oleum leve) materiae rudis. Tamen, in curriculo materiae rudis pretii et maximizationis fructuum, compositiones anilinae saepe utuntur additiva gasolina ligulae. Ut index qualitas gasoline cum talibus additivis occurrat vexillum gasolicum automobile nationali, exempli gratia, addito 1% (fractionis massae) N-methylanilini augere potest numerum octanum per 2-4 unitates [1]. Nihilominus anilina additiva habent pericula potentiale ad mobilitatem et salutem vehiculorum, et N-methylanilines compositorum nitrogeniorum continentium, quae ad augmentum ducunt in contento oxydi nitrogenii in autocineto exhausto, causando effectus nocivos in ambitu atmosphaerico et sanitate humana. . Praecipua partium anilineorum additivorum includunt anilinum, N-methylanilinum, o-methylaninum, p-methylanilinum, M-methylanilinum, N, n dimethylanilinum. In statu, vulgo retulerunt methodos ad detectionem compositorum methylanilinorum includunt naphthalene diethylaminum spectrophotometriam, chromatographiam gasti-nitrogenium chemiluminiscentiae detectionis, chromatographiae liquidae perficiendi altae, etc. [2-4]. Naphthalene diethylaminum spectrophotometriae traditum impedit determinationem effectus propter reactionem lateris occursus, et methodus HPC inevitabiliter afficitur ab impedimento matricis gasolineae.
In chromatographo-nitrogenio chemiluminiscentiae detectionis gasi methodus requirit praeparationem detectoris chemiluminiscentis nitrogenii pretiosae, qui NITROGENIUM selective deprehendere potest. Nuper elaborata (nondum divulganda) vexillum nationale "Gas Chromatographiae pro Determinatione Oxycompoundum et anilinerum Compositionum in Gasoline" describit etiam methodum analysis utendi Decanis in duas columnas oppositas verticitatem utens flammae detectoris communi et respective vilis hydrogenii ion. Ad hanc methodum, ThermoFisher Scientific chartam applicationis emisit (Application Notes C GC-50). Pro simplici, haec charta citius unicam columnam methodum inducit in norma locali DB37/T-2650 edita a Shandong Provincia anno 2015 [5]. Exitus ostendunt hunc modum simplicem ad operandum, cum bona repeatability et accurate alta. Eodem tempore methodus optimized est problema intercessionis quantitatis anilineae per compositionem matricis gasolinam solvendam.
2. Overview principii methodi De polyethylene glycol (PEG) polari, composita anilina in gasolino automotivo a matrice gasoline separata, et acetophenone adhibita ut norma interna. Contenta anilini, N-methylanilini, o-methylanilini, p-methylanilini, m-toluidine et N, n-dimethylanilini gasolinei autocineti determinata sunt a chromatographo gasi ionizationis detectoris flammae instructi (FID), et coniunctio utriusque componentis erat ratione ad internum vexillum.
4: Nuper mercatus postulatio maxima est, nunc omnes ad producendum tendimus, usus technologiae continua methodus productionis, id est, chromatographia gasi.
Intellegimus te solum nos considerare quod tibi aequissimum pretium et optimum qualitatem offerimus. Quaeso vide in catalogo nostro.
