Evaporation with hydrofluoric acid may be omitted.

When smoking with a closed ventilation zone, the smoke yield will clearly increase.

After fuming off the mineral acids, the cobalt remains in hydrochloric acid solution.

An equalization of the smoke yield per draw during test smoking thus is desirable, especially for the purpose of avoiding the change in flavor.

After fuming off the excess acids, the residue is made up to 10 ml with dilute hydrochloric acid.

The excellent fine-fruity aroma is carefully concerted and develops during the smoking to a consummate smoke-pleasure.

The concentration of ilmenite was determined gravimetrically by fuming the samples with hydrofluoric acid, taking into account the loss in weight of pure ilmenite during this treatment.

In the chemical laboratory, there are crucibles, boats, dishes for evaporation, boiling down, melting and disintegration as well as wheel electrodes for the spectral analysis of fluids made from this so-called glass-like carbon.

In order to test the storability, cigarettes provided with chamber filters containing highly porous, granular silica gel charged with 10% by weight anethole and 20% by weight propylene glycol (in each case with respect to the weight of the uncharged carrier material) were smoked under standard conditions and the anethole content present determined during nine draws in the smoke in the particulate phase, shortly after charging the silica gel used and again after around three months, whereby in both cases an anethole content (in the particulate phase) of 0.44 mg/cigarette was determined.

After one cigarette has been removed and smoked, it is reinserted in the cigarette pack, namely in the box, and to be specific, into the waste-compartment designated for this function.

This configuration leads both to an increase in costs and to a complication of the manufacture of this known coaxial cigarette and at the same time the acceptance of this product by the consumer decreases because both an unusual smoke pattern and a reduced smoking experience when smoking this coaxial cigarette result.

This process was repeated until no nitrous vapors were obtained, as was the case after four evaporations.

Especially as regards new type (artificial) cigarettes, which practically keep their full original length after being smoked, this sort of waste-spreading is highly undesirable.

When the flavoured tobacco is smoked a substantially more pronounced fruity note is ascertainable and, in addition, the tobacco note is also clearly intensified.

Nevertheless, the rod produced according to the invention is also air-permeable enough for the combustion air during smoking to be sucked uniformly through the cross section of the rod and the length of the rod, without the suction resistance then provided by the rod exceeding an upper value.

When this rod is smoked, the same process as in a conventionally produced tobacco rod takes place, with the difference that the combustion air is sucked through the set air channels instead of through gaps in the comminuted tobacco.

The crystalline quartz content was determined by diffractometry after repeated evaporation with hydrochloric acid and after calcination to hematite at 800° C. and is less than 0.1%.

Description of the Prior Art One problem experienced in general with conventional cigarettes relates to the fact that with standard smoking they show an increase in the puff-by-puff condensate delivery with increasing smoked length.

In smoking of the first-burning segment, a successive adaptation to the flow conditions in the subsequent segment results, this segment being suitably specified to contribute towards boosting the strength of the first puffs.

Smoking the first-burning segment results in successive adaptation to the flow conditions in the filter-end segment in which--again due to adjustment of the resistances to draw--the smoke is preferably drawn from the jacket with the low condensate potential.

By these means in initial and subsequent smoking of segment 1 smoke is initially drawn preferably from the jacket 1a of this segment 1, resulting in a relative strong taste perception already in initial smoking and in the first puffs of this cigarette.

The resistance to draw ratio q automatically changes during smoking of segment 1 until roughly the resistance to draw ratio q2 of the segment 2 is attained.

By these means it is achieved that in smoking the segment 1 the smoke is initially drawn preferably from the inner core 1a with the high condensate potential of segment 1, resulting in a relatively strong perception of taste during the first puffs.

The excess of the reducing agent was destroyed with glacial acetic acid and the resulting boric acid removed by fuming off with methanol.

Both of the versions of the segmented filter cigarette according to the invention as described above have the advantage, even when formulated as light and ultralight cigarettes, that even in initial smoking and during the first puffs a relatively strong perception of taste results which changes only slightly in the course of further smoking.
