METHOD FOR PREPARING TRIMETHYLOLPROPANE
-
Paragraph 0064-0066, (2020/07/07)
A method for preparing trimethylolpropane, the method including: subjecting dimethylolbutanal (DMB) to a hydrogenation reaction in the presence of a metal catalyst and an alcohol solvent. During the hydrogenation reaction, a weight ratio of the alcohol solvent based to dimethylolbutanal is 2 to 10.
Method For The Combined Production of Polyols In The Presence Of An Inorganic Base
-
Paragraph 0049; 0050, (2019/08/20)
The present invention relates to a process for simultaneously consecutive preparation of polyols by base-catalysed reaction of at least two different mid-chain aldehydes with formaldehyde. The simultaneous consecutive mode of operation makes it possible to achieve high conversions and high selectivities for both aldehydes, with additional achievement of a distinct reduction in the amount of unreacted formaldehyde remaining. This leads to improved process economics, since the energy costs for workup of the formaldehyde stream are distinctly reduced.

Antimony(III) alkoxide cages were designed as building blocks for predictable supramolecular self-assembly. Supramolecular synthons featuring two Sb···O secondary bonding interactions (SBIs), each SBI stronger than 30 kJ/mol, were used to drive the formation of the supramolecular architectures. Judicious choice of pendant groups provided predictable control over the formation of self-assembled 3D columnar helices, which crystallized with hollow morphologies, or a self-assembled 2D bilayer. The Sb-O stretching frequency provides a spectroscopic signature of Sb···O SBI formation.
