    摘要: Distillative process for obtaining ditrimethylolpropane from solutions includes separating ditrimethylolpropane from the solution in a first distillation unit into a first tops fraction comprising low-boiling compounds having a lower boiling point than ditrimethylolpropane and a first bottoms fraction; introducing the first bottoms fraction into a second distillation unit having at least 5 theoretical plates, said unit being configured as a thin-film evaporator with a column attachment and drawing off a second tops fraction comprising intermediate-boiling compounds having a lower boiling point than ditrimethylolpropane as well as withdrawing a second bottoms fraction from the second distillation unit and introducing the second bottoms fraction into a third distillation unit having at least 4 theoretical plates, said unit being configured as a thin-film evaporator with a column attachment, such that ditrimethylolpropane is obtained as a third tops fraction and high boilers are removed as a third bottoms fraction.

    摘要: Applicant has discovered processes for preparing polyglycerols and polyglycerol esters in high yield and with minimal formation of cyclic polyglycerols and cyclic polyglycerol esters. Furthermore, the processes of this invention produce a high proportion of linear polyglycerols and polyglycerol esters. The linear polyglycerols have very desirable physical characteristics, including a clear appearance at melt, a desirable Gardner color, a mild odor, and a bland taste. The polyglycerols and polyglycerol esters prepared by the method of the present invention are well suited for use as cosmetic and food additives. Since few, if any, cyclic polyglycerols and polyglycerol esters are formed by the processes of this invention, costly and time consuming distillation steps to remove such by-products are not needed. More specifically, applicants have discovered that if a calcium containing compound, such as calcium hydroxide, is used in place of potassium or sodium hydroxide during polymerization of glycerol, polyglycerol, or a mixture thereof or esterification of polyglycerols, the formation of cyclic polyglycerols is greatly reduced. One embodiment of the invention is a method of preparing a polyglycerol comprising polymerizing glycerol, polyglycerol, or a mixture thereof in the presence of a calcium containing compound, such as calcium hydroxide. Preferably, the calcium containing compound is present in a catalytically effective amount. Another embodiment is a method of preparing a polyglycerol ester by esterifying a polyglycerol in the presence of a calcium containing compound.

    摘要: The present invention provides a process for recovering ditrimethylolpropane from a still residue obtained by extracting and then distilling off trimethylolpropane from a reaction solution obtained by reacting n-butyraldelhyde with formaldehyde in the presence of a basic catalyst, wherein the still residue is distilled to remove high-boiling components therefrom, and the resultant distillate is subjected to crystallization. When the above process is combined with the acid decomposition, it becomes possible to decompose a linear formal compound obtained from 2 molecules of TMP contained in the still residue as crude TMP and one molecule of formaldehyde, so that di-TMP having a higher purity is obtained.
