| 20100273970 | PROCESS FOR PREPARATION OF HIGH PURITY METHACRYLIC ACID - The present invention relates to a process for preparation of pure methacrylic acid, at least comprising the process steps: a) gas phase oxidation of a C4 compound to obtain a methacrylic acid-comprising gas phase, b) condensation of the methacrylic acid-comprising gas phase to obtain an aqueous methacrylic acid solution, c) separation of at least a part of the methacrylic acid from the aqueous methacrylic acid solution to obtain at least one crude methacrylic acid-comprising product; d) separation of at least a part of the methacrylic acid from the at least one crude methacrylic acid-comprising product by means of a thermal separation process to obtain a pure methacrylic acid. | 10-28-2010 |
| 20110306784 | METHOD FOR PRODUCING A CARBOXYLIC ACID AMIDE FROM A CARBONYL COMPOUND AND HYDROCYANIC ACID - The invention relates to a method for producing a carboxylic acid amide from a carbonyl compound and hydrocyanic acid, comprising the steps of A) reacting a carbonyl compound with hydrocyanic acid to produce a hydroxycarboxylic acid nitrile, B) hydrolysis of the hydroxycarboxylic acid nitrile obtained in step A) in the presence of a catalyst comprising manganese dioxide, wherein a molar excess of carbonyl compound is used in relation to the hydrocyanic acid to react the carbonyl compound with hydrocyanic acid according to step A), and the reaction mixture obtained in step A) is not purified by distillation before the hydrolysis according to step B) is carried out. The invention furthermore relates to a method for producing alkyl(meth)acrylates from polymers, moulding compounds and moulded bodies, wherein a method for producing a carboxylic acid amide from a carbonyl compound and hydrocyanic acid is carried out in accordance with the method described above. | 12-15-2011 |
