| 摘要 |
A process for treating a composition containing a substantial proportion of trimethylolpropane bis-monolinear formal (TMP-BMLF) or trimethylolethane bis-monolinear formal (TME-BMLF), e.g., a heavy ends residue obtained from the purification of a crude trimethylolpropane (TMP) or trimethylolethane (TME) product, wherein the composition is contacted at an elevated temperature with a strong acid catalyst, e.g., methanesulfonic acid, to produce a composition containing significantly increased amounts of TMP and trimethylolpropane monocyclic formal (TMP-MCF) or TME and trimethylolethane monocyclic formal (TME-MCF) respectively. |
