Process of producing a multilayer lignocellulosic composite comprising one or more lignocellulosic composite layers or a single-layer lignocellulosic composite, comprising at least the following steps: a) providing or preparing a mixture at least comprising - lignocellulosic particles and - a binder comprising as components for hardening the binder via esterification at least: ▪ one, two or more polymers comprising multiple carboxyl groups and, for crosslinking said polymers, ▪ one, two or more polymer or monomer compounds having two or more hydroxy groups, wherein the binder comprises as an additional component for hardening the binder via esterification ▪ one or more non-polymeric compounds having two or more carboxyl groups, and/or ▪ one or more non-polymeric compounds having at least one carboxyl group and at least one hydroxy group, b) compacting the mixture, and c) applying a high-frequency electrical field to the mixture during and/or after compacting, so that the binder hardens via esterification of said components and binds the lignocellulosic particles, so that a single-layer lignocellulosic composite or a layer of a multilayer lignocellulosic composite results. a) providing or preparing a mixture at least comprising - lignocellulosic particles and - a binder comprising as components for hardening the binder via esterification at least: ▪ one, two or more polymers comprising multiple carboxyl groups and, for crosslinking said polymers, ▪ one, two or more polymer or monomer compounds having two or more hydroxy groups, wherein the binder comprises as an additional component for hardening the binder via esterification ▪ one or more non-polymeric compounds having two or more carboxyl groups, and/or ▪ one or more non-polymeric compounds having at least one carboxyl group and at least one hydroxy group, - lignocellulosic particles and - a binder comprising as components for hardening the binder via esterification at least: ▪ one, two or more polymers comprising multiple carboxyl groups and, for crosslinking said polymers, ▪ one, two or more polymer or monomer compounds having two or more hydroxy groups, wherein the binder comprises as an additional component for hardening the binder via esterification ▪ one or more non-polymeric compounds having two or more carboxyl groups, and/or ▪ one or more non-polymeric compounds having at least one carboxyl group and at least one hydroxy group, ▪ one, two or more polymers comprising multiple carboxyl groups and, for crosslinking said polymers, ▪ one, two or more polymer or monomer compounds having two or more hydroxy groups, wherein the binder comprises as an additional component for hardening the binder via esterification ▪ one or more non-polymeric compounds having two or more carboxyl groups, and/or ▪ one or more non-polymeric compounds having at least one carboxyl group and at least one hydroxy group, b) compacting the mixture, and c) applying a high-frequency electrical field to the mixture during and/or after compacting, so that the binder hardens via esterification of said components and binds the lignocellulosic particles, so that a single-layer lignocellulosic composite or a layer of a multilayer lignocellulosic composite results.
