Abstract
A presente invenção se refere a um processo para a preparação de dicidal.The present invention relates to a process for preparing dicidal.
Description
[001] A presente invenção se refere a um processo para a preparação de dicidal.[001] The present invention relates to a process for preparing dicidal.
[002] US 2009/0171125 A1 descreve um processo para a hidroformilação de olefinas cíclicas. Neste caso, um catalisador de Rh é usado.[002] US 2009/0171125 A1 describes a process for the hydroformylation of cyclic olefins. In this case, a Rh catalyst is used.
[003] A presente invenção tem o objetivo de prover um inédito processo de hidroformilação. O processo deve proporcionar um aumentado rendimento em comparação com o método conhecido a partir da tecnologia anterior.[003] The present invention aims to provide an unprecedented hydroformylation process. The process should provide an increased yield compared to the method known from the prior art.
[004] Este objetivo é alcançado por um processo como definido na reivindicação 1.[004] This objective is achieved by a process as defined in claim 1.
[005] O processo compreende as etapas do processo de: a) inicialmente carregar diciclopentadieno; b) adicionar um composto da fórmula (I): em que R1, R2, R3, R4, R5, R6, R7, R8são selecionados a partir de: -H, - alquila-(C1-C12), -Ph; c) adicionar um composto de Pt capaz de formar um complexo; d) adicionar um composto de iodo; e) alimentar em CO e H2; f) aquecer a mistura da reação proveniente das etapas a) a e), para converter o diciclopentadieno em dicidal.[005] The process comprises the process steps of: a) initially loading dicyclopentadiene; b) add a compound of formula (I): wherein R1, R2, R3, R4, R5, R6, R7, R8 are selected from: -H, -alkyl-(C1-C12), -Ph; c) adding a Pt compound capable of forming a complex; d) add an iodine compound; e) feed in CO and H2; f) heat the reaction mixture from steps a) to e), to convert the dicyclopentadiene into dicidal.
[006] Neste processo, as etapas do processo a) a e) podem ser efetuadas em qualquer sequência desejada. Tipicamente, entretanto, CO e H2 são adicionados depois que os correagentes foram inicialmente carregados nas etapas a) a d).[006] In this process, process steps a) to e) can be carried out in any desired sequence. Typically, however, CO and H2 are added after the co-agents have initially been loaded in steps a) to d).
[007] Aqui, as etapas do processo c) e d) também podem ser realizadas em uma etapa, por exemplo, pela adição de PtI2.[007] Here, process steps c) and d) can also be carried out in one step, for example, by adding PtI2.
[008] Em uma variante do processo, o composto de Pt e o composto de iodo são adicionados em uma etapa pela adição de PtI2.[008] In a variant of the process, the Pt compound and the iodine compound are added in one step by adding PtI2.
[009] A expressão alquila-(C1-C12) abrange grupos de alquila de cadeia reta e ramificada com 1 a 12 átomos de carbono. Os mesmos são, preferivelmente, grupos de alquila-(C1-C8), mais preferivelmente alquila-(C1-C6), o mais preferivelmente alquila-(C1-C4).[009] The expression alkyl-(C1-C12) covers straight and branched chain alkyl groups with 1 to 12 carbon atoms.
