A contact and separation column () encasing a stack of one or more contact and separation cells (). Each cell comprises: &#x2014;a tray () with gas flow openings () opening into contact and separation units (); &#x2014;a downcomer () defining a liquid discharge; and &#x2014;a liquid supply (). Each contact and separation unit () comprises an upstream contact zone () with liquid inlets (), and one or more downstream separation zones () provided with a swirler () and a top end with a gas outlet (). The swirler () is located at a distance from the gas inlet of from 50 to 90 % of the total length of the contact and separation zone. Process for treating a gas with such a column.

Isocyanate-modified epoxy-functional polyester

Compositions prepared by the glycidation of at least one (a) carboxy polyfunctional polyester and at least one (b) &agr;,&agr;-branched monocarboxylic acid containing a tertiary carbon atom and from 5 to 12 carbon atoms, or a glydicyl ester thereof, a curing agent and, optionally, a catalyst, and coating and or casting compositions containing them.

Glycidation of carboxy polyester and tertiary C monocarboxyic acid (glycidyl ester)

An isocyanate-modified epoxy-functional polyester is prepared by the reaction of an epihalohydrin in the presence of a base with a carboxyl-functional polyester resin (II) obtained by reacting (a) at least one aromatic or (cyclo)aliphatic dicarboxylic acid A having aromatic or secondary carboxyl groups, or the anhydride thereof, (b) at least one diol B having primary or secondary hydroxyl groups, (c) compound C1 having one monofunctional primary or secondary hydroxyl group and/or at least one compound C2 having one primary or secondary hydroxyl group and one tertiary aliphatic carboxyl group, and, optionally, (d) a dihydroxymonocarboxylic acid having a tertiary aliphatic carboxyl group and two aliphatic hydroxyl groups, and/or (e) a trihydroxyalkane (E1) or tetrahydroxyalkane (E2), to produce an epoxy-functional polyester whose terminal hydroxyl groups are reacted with an isocyanate.

Isocyanate-modified epoxy-functional polyester with crosslinking agent

A linear or branched polyglycidylester resin produced by reacting a carboxyl functional polyester resin with an excess epihalohydrin in the presence of a suitable base, wherein the carboxyl functional polyester resin is produced by reacting at a temperature of from 100 to 240.degree. C. at least one dicarboxylic acid compound of the formula ##STR1## wherein x.gtoreq.1 and wherein R.sub.1 and R.sub.2 each represent an alkyl group having from 1 to 4 carbon atoms or wherein R.sub.1 and R.sub.2 form together with the group .about.CH--(CH.sub.2).sub.x --CH.about. a cycloalkylgroup, with at least one diol compound comprising two aliphatic hydroxyl groups, wherein each hydroxyl group independently is a primary or a secondary hydroxyl group, and wherein the number of carboxylic acid groups and anhydrides thereof exceeds the number of hydroxyl groups. The reaction continues until essentially all the hydroxyl groups initially present in the reaction mixture have been reacted.

Acid functional and epoxy functional polyester resins

Compositions, prepared by glycidation of at least one (a) carboxy polyfunctional polyester and at least one (b) .alpha.,.alpha.-branched monocarboxylic acid containing a tertiary carbon atom and from 5 to 12 carbon atoms, or a glydicyl ester thereof, and coating and/or casting compositions comprising them.

Glycidation of carboxyl-functional polyester and 3 C-containing

Process for the preparation of compound of the formula: ##STR1## wherein R.sub.c represents a residue comprising one or more additional groups of the formula: ##STR2## by heating a compound of the formula (A) ##STR3## at a temperature in the range of from 120 to 220.degree. C. in the presence of hydrogen halide addition salt of tertiary amine;
