Title: Continuous sepn. of bisphenol a and phenol from aq. effluents - by liq.-liq. extn. with toluene and distn. of the toluene soln.
IPC: C07C39/16
Filed: 1982-06-24
Abstract: Continuous process for the simultaneous extrn. and isolation of bisphenol A (I) and phenol (II) from the aq. effluent stream obtd. from the purification of (I) with water, is claimed. Process comprises (1) passing the aq.-effluent together with toluene into an extraction vessel; (2) removing the heavier aq. phase from the separator for further processing or disposal; (3) removing a soln. of (I) and (II) in toluene from the top of the separator; (4) recovering (I) and (II) from the toluene soln. and (5) recirculating the toluene to the extraction vessel.

Inventor: SOULIER PHILIPPE
IPC: B65D88/16
Filed: 1989-05-03
Abstract: The container consists of flexible material, essentially of a round fabric made of polyolefins, on whose upper edge in this case four loops (1) are sewn. In this case, the arrangement is such that each loop (1) consists of a relatively wide strip of material, both ends (2, 2') of which overlap the upper container edge (10) and are sewn to the latter spaced apart laterally, and whose central part (3), forming the suspension eye, is drawn together in the manner of a tape. By this means, loops are formed in a relatively simple manner, adjoining which loops there is a large number of warp threads of the round fabric and which in this way have a high load-bearing capacity, the resistance to tensile force at the loops themselves being increased by being drawn together. <IMAGE>
