    摘要: The invention relates to a method for producing an ester from a hydroxybenzoic acid and a fatty alcohol for use in a binder system for powder injection moulding by transesterification of an ester from the hydroxybenzoic acid and a lower alcohol having the fatty alcohol, wherein the fatty alcohol and the ester from the hydroxybenzoic acid and the lower alcohol form a reaction mixture and are used substantially equimolar, wherein the transesterification is carried out at a temperature at which the ester from the hydroxybenzoic acid and the lower alcohol and the fatty alcohol are present as a homogenous melt. The invention furthermore relates to a binder system for a powder injection moulding method, comprising 80 to 98 wt % of a metal powder and/or ceramic powder and 1 to 19 wt % of a polymer binder component, wherein there is furthermore 1 to 19 wt % of at least ester, produced from hydroxybenzoic acid and fatty alcohol according to the method according to the invention.
