Abstract
Official abstract text for this publication.
Cyclic acetals can be produced in a reactive distillation apparatus by combining a polyhydroxyl compound and an aldehyde. High concentrations of cyclic acetals are removed as liquid products from the column while water is removed as an overhead vapor stream.
First claim
Opening claim text (preview).
What we claim is: 1. A liquid composition comprising water in an amount from 0 to 8 mole %, aldehyde compounds in an amount from 0 to 5 mole %, cyclic acetal compounds in an amount from 25 mole % to 75 mole %, polyhydroxyl compounds in an amount from 25 mole % to 75 mole %, and a catalyst in an amount from 0-0.5 mole %, wherein the stated mole percentages are based on the moles of all ingredients within the liquid composition. 2. A liquid composition comprising water in an amount from 0 to 0.5 mole %, aldehyde compounds in an amount from 0 to 0.25 mole %, cyclic acetal compounds in an amount from 50 mole % to 60 mole %, polyhydroxyl compounds in an amount from 40 mole % to 50 mole %, and catalyst in an amount from 0-0.1 mole %, wherein the stated mole percentages are based on the moles of all ingredients within the liquid composition. 3. The composition according to claim 1 , which comprises water in an amount of 0 to 3 mole %. 4. The composition according to claim 1 , which comprises aldehyde compounds in an amount of 0 to 2 mole %.
