Abstract
A process for the preparation of dibutoxymethane, in one embodiment from 50% formaldehyde, in a condensation reaction without the use of co-solvent.
Claims19
A method for preparation of dibutoxymethane from 30-50% formaldehyde, the method comprising:
- providing a 30-50% formaldehyde solution and butanol;
- reacting said 30-50% formaldehyde solution and said butanol in a condensation reaction without the use of a co-solvent for the removal of water.
A dibutoxymethane formed by the process of:
- providing a 30-50% formaldehyde and a butanol;
- reacting said 30-50% formaldehyde and said butanol in a condensation reaction without the use of a co-solvent for the removal of water;
- and
- segregating said dibutoxymethane.

A method for the production of dibutoxymethane, without a recycled butanol discharge, the method comprising the steps of:
- charging water, methanol, paraformaldehyde, and a condensation reaction catalyst together to create a mixture;
- heating said mixture to a temperature at which a clear solution is obtained;
- charging virgin butanol to said mixture;
- heating said mixture;
- collecting water and butanol distillate in a distillation trap;
- cooling said mixture when the accumulation of said water distillate ceases;
- returning said butanol to said mixture;
- charging a neutralization agent to said mixture;
- charging water to said mixture;
- re-heating said mixture to initiate distillation;
- continuing said distillation until a predetermined amount of water has been collected;
- separating a top and a bottom phase of a distillate;
- and
- cooling a mixture residue.
