Abstract: Procedimiento para la obtención de formamida mediante reacción de amoniaco y monóxido de carbono en presencia de al menos un catalizador y al menos un alcohol en un reactor, caracterizado porque la mezcla de reacción que contiene formamida se traslada del reactor a una instalación separada, y se elabora en la misma, y el catalizador presente como metanolato sódico y/o diformilamida sódica se separa en esta instalación, y se devuelve al reactor o componente de una mezcla que contiene formamida.

Abstract: A description is given of a process for preparing methyl formate by reacting excess methanol with carbon monoxide under superatmospheric pressure and at elevated temperature in the presence of alkali metal methoxide or alkaline earth metal methoxide as catalyst in a pressure-rated reactor, in which the use of at least two reactor elements, preferably operated in countercurrent, at about 100° C. and a pressure of about 100 bar in combination with a solids-free desalting of the reaction product makes possible very economical, largely trouble-free production of methyl formate in any desired quality and with a very good production capacity. Furthermore, the process for solids-free desalting and apparatuses for carrying out this process are described.

Abstract: A process for preparing butenyl ethers of the formula Iby reacting butadiene or butadiene-containing hydrocarbon streams with alcohols of the formula IIat elevated temperature and superatmospheric pressure in the presence of transition metal complexes containing ligands of compounds of elements of group V of the Periodic Table of the Elements to form an isomer mixture of butenyl ethers of the formula I and butenyl ethers of the formula IIIand, optionally, isomerizing the butenyl ethers of the formula III to butenyl ethers of the formula I, where R is as defined in the specification and the catalyst used is a complex of a transition metal of group VIII of the Periodic Table of the Elements with ligands of the formula IVwhere M is an iron, cobalt, nickel, or ruthenium atom, X is a bridge and where n, y and R1-R6 are as defined in the specification.
