Organic chlorohydrosilane and method for preparing them

Номер: US20120114544A1
Автор: Eun Seong Kim, Il Nam Jung, Sang Il Hyun, Soon Hyun Hong
Принадлежит: Samsung Fine Chemicals Co Ltd

Provided is an organic chlorohydrosilane, a useful starting material for preparing silicon polymers and a method for preparing the same. More particularly, the present invention enables the synthesis of various novel organic chlorohydrosilanes in high yield by an exchange reaction between an Si—H bond of a chlorosilane which can be obtained in an inexpensive and easy manner and an Si—Cl bond of an another organic chlorosilane using a quaternary organic phosphonium salt compound as a catalyst. Since the catalyst can be recovered after its use and reused, the present invention is very economical and thus effective for mass-producing silicon raw materials.

The invention relates to a process for producing oxamide-functional siloxanes.Oxamide-functional polysiloxanes can be used in many fields of application, but especially for producing block copolymers of thermoplastic siloxanes such as are described, for example, in EP-A 1 963 404. The production of such oxamide-functional siloxanes is known in principle and described in US-A 2007/0149745. Bisaminoalkyl-functional siloxanes are used as starting products in this case which can be prepared by various methods. These bisaminoalkyl-functional siloxanes are preferably reacted with dialkyl oxalates, present in excess, to give the desired substituted amino-oxo-acetate-functional siloxanes, referred to below simply as oxamide-functional siloxanes. For further conversion of these products, the excess of dialkyl oxalates present in the reaction mixture generally also have to be removed, which is accomplished here particularly by vacuum distillation.

Solid-phase catalysts comprising a frustrated Lewis pair (FLP) immobilized on a support having a hydroxylated surface are disclosed. Also described are methods of making the solid-phase catalysts as well as their uses in hydrogenation reactions of olefins. The solid-supported FLPs present numerous catalytic advantages over FLPs known heretofore, including reduced reactor fouling, improved separation procedures and the ability to use the catalysts in continuous flow applications. Preferred FLPs comprise B(C6F5)3, B(C6CI5)(C6F5)2, P(tBu)3 and tetramethylpiperidine (TMP); preferred supports are silica and layered double hydroxides, in particular hydrotalcite.

본 명세서는 올리고머화 촉매계의 제조방법에 관한 것으로, 구체적으로 PNP계 리간드 화합물 및 전이금속 화합물을 혼합하여 촉매조성물을 제조하는 단계; 및 조촉매와 상기 촉매조성물이 온도 -40 내지 80℃에서 혼합되어 활성화 되는 단계;를 포함한다. 이와 같은 방법을 통해 제조된 올리고머화 촉매계는 올리고머화 반응시 고온에서도 활성이 저하되지 않고 유지될 수 있으며, 이에 따라 올리고머화 반응의 온도 제어가 용이하여 다양한 공정상의 이점을 가질 수 있다. The present invention relates to a process for preparing an oligomerization catalyst system, and more particularly, to a process for preparing a catalyst composition by mixing a PNP-based ligand compound and a transition metal compound; And a step in which the cocatalyst and the catalyst composition are mixed and activated at a temperature of -40 to 80 캜. The oligomerization catalyst system produced by such a method can be maintained at an elevated temperature without lowering the activity during the oligomerization reaction, so that temperature control of the oligomerization reaction can be easily performed, and thus various process advantages can be obtained.
