Title (EN) 1,2-ALKANEDIOLS AND A PROCESS FOR THEIR PRODUCTION
(FR) 1,2-ALCANEDIOLS ET PROCÉDÉS DE PRODUCTION DE CES DERNIERS
Abstract:
(EN) Suggested are 1,2-alkanediols of formula (I) HOCH2-CH(OH)-R1 in which R1 stands for an alkyl radical having 3 to 10 carbon atoms, said diols being substantially free of lactones and/or peroxides.
(FR) La présente invention porte sur des 1,2-alcanediols de formule (I) HOCH2-CH(OH)-R1 dans laquelle R1 représente un radical alkyle ayant de 3 à 10 atomes de carbone, lesdits diols étant sensiblement exempts de lactones et/ou de peroxydes.
