PIPE UNIT FOR INTRODUCTION OF CYCLOHEXANONE OXIDE INTO REARRANGED PRODUCT Russian patent published in 2008 - IPC B01F5/00 B01F5/04 

FIELD: chemical industry.

SUBSTANCE: invention relates to pipe units for introduction of cyclohexanone oxide into rearranged product at production of capropactam. According to invention, pipe reel 3 with perpendicularly welded-to union 4 for introduction of cycloheaxanone-oxide into rearranged product is fitted in pipe unit by means of flange joints 2. Union 4 is connected with interbranch space 13 formed in pipeline by two cross partitions 5 and 6. Cross partitions are arranged in direction of flow of rearranged product and are installed on ends of branch pipes 7 with inlet drilled channels 14. Axes of channels 14 are located at distances equal to not more than half of diameter of branch pipes from plane of inlet partition 5.

EFFECT: provision of safe conditions for introduction of cycloheaxanone oxime onto rearranged product at production of caprolactam by excluding possibility of getting of rearranged product into cyclohexanone oxime delivery line.
