Embodiment 1

[0089] The non-aqueous hydroformylation product solution (174.5 g) obtained from the preparation example contained 2-methyl-1,3-propanediol (MPO), methanol and water in a weight ratio of 1:7:2 (MPO:methanol: Water) and aqueous extraction solvent were mixed at a mass ratio of 1:1 (non-aqueous hydroformylation product solution: aqueous extraction solvent), and stirred in a mixer whose temperature was kept at 25°C. After stirring for 1 hour, the mixture was poured into a glass extractor and allowed to stand for 2 hours to obtain a biphasic mixture (non-aqueous hydroformylation solvent layer (i.e., non-polar phase) and aqueous extraction solvent layer (i.e., polar phase). phase). The extraction temperature was maintained at 25°C. After that, 0.5g of Ni / Al 2 o 3 100 g of the aqueous phase extraction layer was added, and a hydrogen pressure of 5 MPa was introduced to carry out a hydrogenation reaction at a temperature of 60° C. for about 3 hours. Afterwards, the hydrogenated produ...

Embodiment 2

[0091] Obtained from the non-aqueous hydroformylation product solution (174.5g) of preparation example and containing tricyclic [5.2.1.0 (2,6)] decane dimethanol, methanol and water and weight ratio 1:7:2 (tricyclic [5.2.1.0 (2,6)] The aqueous extraction solvent of decane dimethanol:methanol:water) is mixed at a mass ratio of 1:1 (non-aqueous hydroformylation product solution: aqueous extraction solvent), and kept at temperature Stir in a mixer at 35°C. After stirring for 1 hour, the mixture was poured into a glass extractor and allowed to stand for 2 hours, resulting in a biphasic mixture. The extraction temperature was maintained at 35°C. After that, 0.5g of Ni / Al 2 o 3 100 g of the aqueous phase extraction layer was added, and a hydrogen pressure of 8 MPa was introduced to carry out a hydrogenation reaction at a temperature of 80° C. for about 3 hours. Afterwards, the hydrogenated product (252.4 g) was distilled at a pressure of 10 hPa in a Kirschner distillation head w...

Abstract

Tricyclodecane dimethanol-based compositions are provided which contain specific amounts of components and allow for improved fluidity and optical properties of products made therewith.

Description

technical field [0001] The present invention relates to a novel composition containing tricyclodecanedimethanol which is suitable as a raw material for the manufacture of transparent optical materials. Background technique [0002] All publications mentioned herein are incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference. The following description includes information to assist in the understanding of the present invention. No admission is made that any of the information provided herein is prior art or that any publications to which, either expressly or implicitly referenced, are prior art with respect to the invention described herein. [0003] Optical materials or polymeric materials used for electronic parts and the like are generally required to have high transparency. This is at least due to ease of handling, such as allowing multiple light sour...
