摘要： A binder composition is disclosed, which comprises:(A) a copolymer emulsion which contains as its essential ingredients vinyl acetate, ethylene, and a monomer represented by the formula (1): ##STR1## wherein R.sub.1 is H or CH.sub.3 ; and R.sub.2 is H or an alkyl group having not more than 5 carbon atoms, the proportions of the respective ingredients being within the range of 55-96.5/3-40/0.5-5 on a weight basis;(B) a formaldehyde-free nitrogen-containing glyoxal resin;(C) a metal salt catalyst; and optionally(D) a higher alcohol sulfuric acid ester-based surfactant.Nonwoven fabrics and impregnated papers using the binder composition are also disclosed. The binder composition exhibits not only high resistance to water and solvents but also low residual free formaldehyde level, with an improvement in foamability being optionally attainable.

摘要： A high melting, high boiling organic compound is easily and stably purified by continuously supplying the molten organic compound to a rectification zone under a subatmospheric pressure and continuously distilling off and recovering vapors from the top of the rectification zone, while continuously withdrawing bottoms containing higher boiling impurities and/or involatile impurities than the desired compound from a reboiling zone at the bottom of the rectification zone to the outside of rectification system by means of a barometric leg, without any pretreatment of removing lower boiling impurities therefrom before the rectification, and without disturbing a pressure balance in the rectification system.
