example 1

[0027]Put the coniferous wood into a pulverizer and pulverize it for 3 hours to obtain sawdust. Put 200g of sawdust and 250mL of water into a beater for beating for 2 hours to obtain coniferous wood pulp. Add 40mL of sodium hydroxide with a mass fraction of 40% to the coniferous wood pulp solution, heated up to 100°C, heat-preserved and cooked for 4 hours, filtered to separate and remove the filtrate to obtain delignified wood pulp; put the above-mentioned delignified wood pulp in a stirred tank, and add 30mL of 5% aluminum chloride solution, start the agitator, stir and mix at a speed of 200r / min for 30min, then feed a mixed gas of propylene and acetyl chloride with a volume ratio of 3:1 into the wood pulp at a ventilation rate of 30mL / min at room temperature , after ventilating for 30min, seal the stirred tank, stir and react for 3h, and obtain the wood pulp that emits aroma; ZnCl with a concentration of 4.0mol / L 2 Solution and CuCl with a concentration of 0.3mol / L 2 Mix th...

[0031] Put the coniferous wood into a pulverizer and pulverize it for 4 hours to obtain sawdust. Put 220g of sawdust and 300mL of water into a beater for beating for 3 hours to obtain coniferous wood pulp. Add 50mL of sodium hydroxide with a mass fraction of 40% to the coniferous wood pulp solution, heated to 110°C, heat-preserved and cooked for 5 hours, filtered to separate and remove the filtrate, and obtained delignified wood pulp; put the above-mentioned delignified wood pulp in a stirred tank, and add 40 mL of aluminum chloride solution, start the agitator, stir and mix at a speed of 250r / min for 40min, then feed a mixed gas of propylene and acetyl chloride with a volume ratio of 3:1 into the wood pulp at a ventilation rate of 40mL / min at room temperature , after ventilating for 35 minutes, seal the stirred tank, stir and react for 4 hours, and obtain the wood pulp that emits aroma; ZnCl with a concentration of 4.0mol / L 2 Solution and CuCl with a concentration of 0.3mol / L...

Abstract

The invention discloses a preparation method of aromatic tar-reducing cigarette paper, and belongs to the technical field of paper product preparations. The preparation method is characterized by thata softwood pulp is subjected to alkali cooking treatment to produce a delignified wood pulp; and a mixed gas of propylene and acetyl chloride is introduced into the wood pulp, and trans-3-pentene-2-dione is produced in the wood pulp under a catalytic action of aluminum chloride, so that an aroma-emitting wood pulp is obtained. According to the preparation method, a principle that a Fridel-Craftsreaction of an alkene with an acid halide yields a corresponding alpha,beta-unsaturated ketone is used, after lignin is removed from the wood pulp, burning of the cigarette paper will not produce a wood gas with a sour and astringent taste, and a scent will go into mouth, so that both of the taste and the odor of the cigarette paper are improved; and softwood fiber is long and soft, and has thin cell walls and large cell cavities, so that the softwood fiber is easy to fibrillate during a beating process, and fibers are combined tightly to each other, and after the delignification, the porosityof the fibers is improved, so that the amount of oxygen is increased when a cigarette is burned, thereby making tar fully burned, and achieving a purpose of reducing tar in the cigarettes, therefore,the aromatic tar-reducing cigarette paper has a wide application prospect.

Description

technical field [0001] The invention discloses a method for preparing flavor-type reduced-tar cigarette paper, which belongs to the technical field of paper product preparation. Background technique [0002] Cigarette paper includes straight rib cigarette paper, horizontal rib cigarette paper and anti-counterfeit cigarette paper and other types of cigarette paper. According to the quality, it is divided into three grades: A, B and C. The air permeability is high, ranging from 30 to 110 CU, and the filter rod paper is between 3000 and 7000 CU. Cigarette paper has the characteristics of clear ribbing, uniform uniformity, and high strength. [0003] With the public's increasing attention to smoking and health issues, the harmful components released in cigarette smoke have gradually become the focus of people's attention, and their release has become an important parameter for evaluating the harmfulness of cigarettes. [0004] Cigarette paper is an important material in cigare...
