Abstract

Le proprietà di un prodotto di reazione vengono previste dai reagenti dai quali esso viene formato effettuando analisi spettrali sui reagenti ed effettuando un'analisi di fattore di fattori quantitativi derivati da spettri. Le analisi spettrali vengono effettuate sui reagenti nel miscuglio in cui verranno fatti reagire e la reazione è generalmente una che comporta la conversione chimica di due o più specie ad un prodotto chimicamente distinto, singolo, facoltativamente in presenza di altri componenti non reagenti. L'analisi di fattori è basata su informazioni derivate da miscugli noti che per reazione producono prodotti di quantità di proprietà note e mostrano ancora variazione sufficiente tra essi per prevedere in maniera adeguata il tipo e grado di variazione da scoprire nel campione di prova.The properties of a reaction product are predicted by the reactants from which it is formed by carrying out spectral analyzes on the reactants and by carrying out a factor analysis of quantitative factors derived from spectra. The spectral analyzes are carried out on the reactants in the mixture in which they will be reacted and the reaction is generally one which involves the chemical conversion of two or more species to a chemically distinct, single product, optionally in the presence of other non-reactive components. The analysis of factors is based on information derived from known mixtures which by reaction produce products of quantities of known properties and still show sufficient variation between them to adequately predict the type and degree of variation to be discovered in the test sample.
