Abstract

Patente de Invenção: <B>"PROCESSO PARA MELHORAR O ODOR DE SOLVENTE COMERCIAL EMPREGADO EM COMPOSIçõES AMACIANTES DE TECIDO"<D>. O 2,2,4-trimetil-1,3-pentanodiol comercialmente disponível é processado por redução, hidrogenação, recristalização, tratamento de de permuta de íon, destilação fracional, tratamento de base, extração aquosa, extração de vácuo, pulverização de nitrogênio, ou as combinações destes para melhorar seu odor reduzindo-se as concentrações de fase de gás de materiais odorizantes tipicamente encontrados no 2,2,4-trimetil-1,3-pentanodiol comercialmente disponível. O 2,2,4-trimetil-1,3-pentanodiol resultante tendo odor melhorado é empregado em várias composições amaciantes de tecido.Invention Patent: <B> "PROCESS TO IMPROVE THE ODOR OF COMMERCIAL SOLVENT USED IN TISSUE SOFTENING COMPOSITIONS" <D>. The commercially available 2,2,4-trimethyl-1,3-pentanediol is processed by reduction, hydrogenation, recrystallization, ion exchange treatment, fractional distillation, base treatment, aqueous extraction, vacuum extraction, nitrogen spray, or combinations of these to improve their odor by reducing the gas phase concentrations of odorizing materials typically found in commercially available 2,2,4-trimethyl-1,3-pentanediol. The resulting 2,2,4-trimethyl-1,3-pentanediol having improved odor is employed in various fabric softening compositions.
