摘要:
The ash characteristics of a cigarette paper wrapper are improved by using fine particle size calcium carbonate filler. In addition, increased calcium carbonate filler loading level, increased basis weight, and various combinations of these variables are used to achieve improved ash characteristics.
摘要:
The sidestream smoke associated with a cigarette or cigarette-like smoking article is reduced by wrapping the tobacco in a paper wrapper having an additive, such as an organic acid, an acidic or neutral salt or an organic acid in combination with an acidic salt or neutral salt added thereto.
摘要:
A smoking article in which a flavored aerosol is generated by heat transfer to a flavor bed from the combustion of a heat source is provided. The article generates substantially no sidestream smoke. The transfer of heat from the heat source to the flavor bed is accomplished by convective and radiative heat transfer.
摘要:
A smoking article in which a flavored aerosol is generated by heat transfer to a flavor bed from the combustion of a carbon heat source is provided wherein the carbon heat source and the flavor bed are contained within a non-combustible substantially cylindrical hollow ceramic sleeve. The article generates substantially no sidestream smoke. The transfer of heat from the heat source is accomplished by convective and radiative heat transfer.
摘要:
A paper wrapper for a cigarette is prepared using fine particle size calcium carbonate as the mineral filler for the purpose of burn rate, puff count and tar delivery control.

摘要:
A method is disclosed for preparing chiral nicotine and nicotine analogues of the formula: ##STR1## wherein R.sub.1, R.sub.2, and R.sub.3 are hydrogen or alkyl and R.sub.4 is alkyl. Also disclosed are novel intermediate compounds and a novel method for preparing 1-methylprolinol from prolinol, which compounds and method are useful for the preparation of these nicotinoids.
摘要:
The production of 2-cyano N-substituted heterocyclic compounds by a process which involves the reduction of N-substituted lactams followed by reaction of the intermediate product with cyanide is described. This process permits the production of many known and novel compounds.
