    • A process is proposed for preparing hydroxyaromatics by heterogeneous catalytic reaction of hydroxyaromatics with C1-C4-alkanols in a microreactor (10), comprising the steps of: a) introducing the hydroxyaromatic and at least one compound selected from the group consisting of C1-C4-alkanols as reactants into at least one inlet orifice (22) of the microreactor (10) comprising at least one microreactor unit (18), b) passing the reactants through at least one microreactor unit (18) of the microreactor (10), said unit comprising a multitude of microchannels (28), said microchannels (28) having a lateral extent of less than 1 mm, and a heterogeneous catalyst being incorporated in the microchannels (28) for conversion of the reactants, c) passing the hydroxyaromatics prepared out through at least one outlet orifice (24) of the microreactor (10).
    • 提出了一种通过羟基芳烃与微量反应器(10)中的C 1 -C 4 - 链烷醇的非均相催化反应制备羟基芳族化合物的方法,包括以下步骤:a)引入羟基芳族化合物和至少一种选自C1-C4 至少一个包含至少一个微反应器单元(18)的微反应器(10)的入口孔(22)中的反应物作为反应物,b)使反应物通过微反应器(10)的至少一个微反应器单元(18) 所述单元包括多个微通道(28),所述微通道(28)具有小于1mm的横向范围,并且将多相催化剂并入所述微通道(28)中以转化所述反应物,c)使所述羟基芳族化合物 通过微反应器(10)的至少一个出口孔(24)排出。
