Abstract
"PROCESSO PARA A PREPARAçãO DE UM COMPOSTO". A presente invenção apresenta um processo isento de solvente para a hidrogenação catalítica de ésteres do ácido 4,4,4-trihaloacetoacético usando um catalisador de platina na presença de um co-catalisador ácido ou básico para fornecer um éster hidroxibutirato análogo. Tais ésteres 3-hidroxibutirato são úteis como solventes, limpadores ou intermediários de química fina.
