Low-VOC polyamino alcohols
View Patent ↗A method for producing a polyamino-polyalcohol. The method comprises steps of: (a) combining an aminoalcohol of formula (I) with a nitro-diol of formula (II) to produce a nitro amino diol; and (b) contacting the nitro amino diol with a reducing agent capable of reducing aliphatic nitro groups.
1. A compound having formula (III)
wherein R 2 and R 3 independently are hydrogen, methyl, ethyl, hydroxymethyl, or R 2 and R 3 combine with a carbon to which they are attached to form a five-membered or six-membered saturated carbocyclic ring; R 4 is hydrogen or C 1 -C 4 alkyl; R 5 is hydrogen, methyl, ethyl or hydroxymethyl; R 6 is hydrogen, hydroxyethyl, C 1 -C 10 alkyl or —CH 2 C(R 5 )(N(R 7 ) 2 )CH 2 OH; and R 7 is hydrogen or methyl.
2. The compound of claim 1 in which R 2 and R 3 independently are methyl or ethyl; R 4 is hydrogen; R 5 is methyl or ethyl; and R 6 is hydrogen or —CH 2 C(R 5 )(NH 2 )CH 2 OH.
3. The compound of claim 2 in which R 2 , R 3 and R 5 are methyl.
