摘要： A process for the production of ethylene glycol comprising: (i) supplying ethylene and oxygen and an organic chloride moderator to an EO reactor, thereby producing a reactor product stream; (ii) supplying the reactor product stream to an EO absorber, thereby producing a fat absorbent stream; (iii) supplying the fat absorbent stream to an EO stripper, thereby producing a concentrated ethylene oxide stream and a lean absorbent stream; (iv) recirculating the lean absorbent stream to the EO absorber; and (v) supplying the ethylene oxide stream and/or the ethylene carbonate stream to hydrolysis reactors with an alkali metal salt hydrolysis catalyst to form an ethylene glycol stream; wherein the process additionally comprises: (vi) removing a glycol bleed stream from the ethylene oxide stripper; and (vii) adding a base to the ethylene oxide stripper such that the pH in the bottom section of the stripper is maintained from 9.5 to 12.0.

摘要： Waterborne sanitary can coating composition, derived from at least (a) epoxy resin, derived from phenol derivatives and epichlorohydrin, which has been converted into a cationic NH2 containing form by reaction with amine, an amine adduct or ammonia and subsequently has been converted into corresponding ammonium salt by addition of organic acid, (b) a phenol-formaldehyde resin as curing agent, (c) polyketone resin, having a number average molecular weight Mn of at least 500, and (d) water, containing minor amounts of organic solvents. Coated tin plate coils on which said waterborne sanitary compositions have been applied and coated cans, obtained from the coated tin plate coil.
