Abstract: An insert for inclusion in a substantially sealed container to control the relative humidity within the container is provided. The insert is a packet at least part of the surface of which is a membrane capable of passing water vapor and which contains a buffering substance which is a saturated salt solution selected according to the desired relative humidity, and modified by a nonelectrolyte, if necessary, to adjust the relative humidity.

Abstract: This invention provides an efficient two-step reaction sequence for producing N-t-butyl-p-menthane-3-carboxamide. The process involves forming 3-p-menthylmagnesium halide, and reacting the 3-p-menthylmagnesium halide with t-butyl isocyanate to form the product.

Abstract: A unitary pack of smoking tobacco products is provided in which a flavorant is incorporated in some of the smoking tobacco products in the form of a polymeric alcohol flavorant-release composition which has the general formula: ##STR1## wherein R is selected from aliphatic, alicyclic, heterocyclic and aromatic hydrocarbon radicals; R.sup.1 and R.sup.2 are selected from hydrogen and aliphatic, alicyclic, heterocyclic and aromatic hydrocarbon radicals; and n is an integer. These polymers release a flavorant when heated. Such polymers include polymers formed from .alpha.-substituted vinyl menthyl carbonate esters, such as poly(.alpha.-methylvinyl .alpha.-menthyl carbonate) and poly(.alpha.-styryl .alpha.-menthyl carbonate), which release menthol when heated. Smoking tobacco products which are made with tobacco which has been treated with a particular alcohol flavorant-release composition have been found to show no significant loss in delivery of flavor.

Abstract: This invention provides tobacco compositions which contain a flavorant-release oligomeric and polymeric derivative corresponding to the structural formula: ##STR1## wherein R is a member selected from the group consisting of hydrogen and aliphatic, alicyclic and aromatic hydrocarbon radicals containing between 1 and about 10 carbon atoms, with the proviso that R is hydrogen when m is zero; R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are members selected from the group consisting of hydrogen and aliphatic, alicyclic and aromatic hydrocarbon radicals; and m and n are integers.

Abstract: This invention provides .alpha.-substituted-vinyl menthyl carbonate esters, and further provides menthol-release oligomeric and polymeric derivatives thereof corresponding to the formula: ##STR1## WHEREIN R is a member selected from the group consisting of aliphatic, alicyclic and aromatic hydrocarbon radicals containing between 1 and about 10 carbon atoms, and n is an integer varying between 2 and about 200.This invention further provides a smoking composition comprising an admixture of tobacco and a polymeric composition as described herein as a menthol-release agent.
