摘要： The present invention relates to a process for cleaving a (meth)acrylic acid oligomer of structure I wherein R1 is a hydrogen atom or a C1 to C10 alkyl groups, R2 is a hydrogen atom or a methyl group, and n is a whole number within the range between 1 and 200, optionally in the presence of a cleaving agent of the structure R3—OH or of the structure (R4)2—N—H, whereby R3 is a hydrogen atom, a C1 to C12 alkyl group, or a —CxH2x—OH— group, whereby x is a whole number within a range from 1 to 12, and R4 is a hydrogen atom or a C1 to C12 alkyl group, with the proviso that not both R4 groups are hydrogen atoms, whereby the (meth)acrylic acid oligomers are heated with the cleaving agent to a temperature of at least 50° C. at a pressure of at least 1 bar. The present invention also relates to the use of water, optionally with a protic compound as cleaving agent for cleaving (meth)acrylic acid oligomers, a device for (meth)acrylic acid synthesis, the use of this device for production of (meth)acrylic acid, as well as (meth)acrylic acid which has been produced using this device.
