PENCEGAHAN, PENGELUARAN ATAU PENGURANGAN ENDAPAN-ENDAPAN PADA BAGIAN-BAGIAN PERALATAN DALAM ESTERIFIKASI ASAM AKRILAT ATAU METAKRILAT

摘要

In the preparation of esters of acrylic or methacrylic acid by esterification with alcohols, the interfering deposits formed on the apparatus parts by relatively high molecular weight by-products can be avoided, removed or lessened by allowing a liquid partly or wholly consisting of the alcohol used for the esterification to act on the deposits, fouled apparatus parts or on the surfaces of the apparatus parts on which deposits are easily formed, with preference being given to wetting the deposits or surfaces using suitable nozzles or cleaning sprayers.
