Problems solved by technology

[0005] To sum up, some explorations and researches have been carried out at home and abroad on how to effectively reduce the release of phenol in cigarette smoke. These work mainly focus on the treatment of tobacco leaves and shredded tobacco, and the treatment of filter rods (additives). No research work has been done to selectively reduce the release of phenol in cigarette smoke by adding macroporous adsorbent resin to the mouthpiece

Abstract

The invention discloses a macroreticular resin capable of lowering the content of phenyl hydroxide in cigarette smoke and a preparation method thereof. The macroreticular resin comprises the following components in parts by mass: oil phase: 20-30 parts of phenethylene, 10-30 parts of cross-linking agent, 40-60 parts of pore-foaming agent and 1-2 part (s) of initiator; water phase: 300-400 parts of deionized water, 2-3 parts of dispersant and 25-40 parts of NaCl; the mass ratio of the oil phase to the water phase is 1: (3-4). The macroreticular resin provided by the invention can effectively and selectively reduce the release amount of phenyl hydroxide in mainstream smoke of cigarettes by more than 30%, and the addition amount of the macroreticular resin in a mouthpiece can be optionally adjusted as required; the macroreticular resin can selectively absorb poisonous substances such as phenyl hydroxide in smoke while keeping the smoke aroma unchanged and the release amount of tar oil approximately unchanged or slightly reduced without causing adverse impact on the smoking quality of cigarettes, thereby achieving the purpose of selectively reducing the release amount of phenyl hydroxide in cigarette smoke.

Description

Technical field [0001] The invention relates to a preparation method of a macroporous adsorption resin, in particular to a macroporous adsorption resin for reducing the content of phenol in cigarette smoke and a preparation method thereof. Background technique [0002] Macroporous adsorption resin is a kind of macroporous adsorption resin that does not contain exchange groups and has a macroporous structure. It is an organic polymer polymer that is insoluble in acids, alkalis and various organic solvents. It is a class developed in modern times. Organic polymer adsorbent. The separation technology using macroporous adsorption resin is one of the new separation technologies developed in the late 1960s after ion exchange resin, and has been widely used in environmental protection, food, traditional Chinese medicine, metallurgy and other fields. It has many advantages such as high physical and chemical stability, large specific surface area, large adsorption capacity, good selectiv...
