Provided is an artificial leather which can be used as a surface material or interior material of a sheet for interior decoration, automobile, aircraft, train, etc., clothing products, etc., and which takes into account texture (softness and hardness value), density (dispersion of fiber bundles) and moist feeling (resin blocks of appropriate size). The artificial leather of the present invention is characterized in that it is an artificial leather comprising a fiber sheet and a polyurethane resin, the fiber sheet at least comprising a fiber layer (A), the fiber layer (A) constituting a first outer surface of the artificial leather, and the k-neighbor distance ratio value (k=9, radius r=20μm) between single fiber cross sections constituting the fiber layer (A) in a thickness direction cross section of the artificial leather is 10% or more and 80% or less, and the cross-sectional polyurethane resin area ratio in the thickness direction cross section of the aforementioned fiber layer (A) is 10% or more and 30% or less, and the standard deviation of the cross-sectional polyurethane resin area ratio in the thickness direction cross section of the aforementioned fiber layer (A) is 25% or less.

The invention discloses an aerosol generating substrate and an aerosol generating system. The aerosol generating substrate comprises 2-hydroxyacetone and propylene glycol. According to the application, the 2-hydroxyacetone is added into the aerosol generating substrate and replaces part of propylene glycol in the aerosol generating substrate, so that the particle size of the aerosol generated by atomization can be effectively increased, the release of formaldehyde is reduced, and the safety problem of heating atomization of the aerosol generating substrate in related technologies is improved; meanwhile, the 2-hydroxyacetone is used as a natural humectant, so that the dryness of the aerosol can be reduced, the moist feeling of the aerosol can be improved, the keto-sweet feeling can be increased, and the use experience of a user can be improved.

The invention discloses a method for synthesizing menthol amine compounds and their application in cigarettes. In an air environment, menthol and bromoacetyl bromide are placed in a reaction container, a first additive is added, a first step reaction is carried out in a first solvent, and then an amine derivative and a second additive are added, and a reaction is carried out in a second reaction solvent to prepare menthol amine compounds, wherein the reaction formula is: The menthol amine compound prepared by the invention is a common biologically active molecular structure and has a wide range of biological properties, including antibacterial, anti-inflammatory and antiviral activities. In particular, the menthol amine compound prepared by the invention has a more penetration-promoting effect, promotes the transdermal penetration of drugs, and is non-irritating and non-toxic to the skin.

This invention provides a centrifugal system and method for concentrating and removing impurities from tobacco alcohol extracts obtained through papermaking. The system includes a first feeding tank, a separator, and a second concentrated liquid feeding tank. The first feeding tank is equipped with a vertical stirrer, and has a concentrated liquid inlet, a reflux port, and a clean water inlet at the top, and an outlet at the bottom. The separator has an inlet and an outlet at the top. The second concentrated liquid feeding tank has a concentrated liquid inlet, a reflux port, and a clean water inlet at the top, and an outlet at the bottom. A concentrated liquid feeding pipeline is connected to the concentrated liquid inlet of the first feeding tank. The outlet of the first feeding tank is connected to both the reflux port of the first feeding tank and the inlet of the separator. The outlet of the separator is connected to the concentrated liquid inlet of the second concentrated liquid feeding tank. The outlet of the second concentrated liquid feeding tank is connected to both the reflux port of the second concentrated liquid feeding tank and a concentrator / evaporator. This system can effectively reduce the content of large-molecule insoluble matter in tobacco alcohol extracts and improve the quality of the extracts.
