Perfumer Ernest Beaux was an experimental chemist. The legend says: when Mademoiselle Chanel, in defiance of the fashion for monofloral scents, asked him to create a new, abstract fragrance, Beau overreacted. During experiments with unstable aldehydes, which make floral notes airy, he accidentally upset the proportions - and could no longer stop. So, let's figure it out Chanel No. 5 Parfum by ingredients

The article describes some of the most dangerous chemical poisons and their effect on the human body. We wish you never to come into contact with these substances. Poison is a substance that, even in small doses, leads to a detrimental effect on the body: poisoning, illness and death. Poisons are usually depicted with the sign of a skull and crossbones. Chemical poisons are produced by synthesizing various substances.
Acrolein
It is a colorless, highly toxic liquid with a tear effect and is highly volatile. The substance was used in the First Pestilence War as a chemical weapon. Acrolein, when inhaled, is highly irritating to the mucous membrane and respiratory tract. It is synthesized during the thermal decomposition of glycerol.
Soman- colorless combat liquid with the smell of apples. It has a nerve paralytic property, the first symptoms are noticeable minutes after the lesion - the pupils dilate, breathing becomes difficult. First used in 1944.
Carbon disulfide
Carbon disulfide is a liquid with a pleasant odor, but extremely poisonous. A lethal dose of 1 gram has a narcotic effect. Symptoms: loss of consciousness, convulsions, severe headache. Also vomiting, intermittent breathing, chemical burns (skin contact).
Trimethylamine- The gas is colorless and has the odor of ammonia. Low concentrations of the gas cause eye irritation and irritation of the mucous membrane of the respiratory tract. At higher concentrations it suffocates.
Phosgene– a colorless toxic gas with the smell of hay. Poisonous if vapors are inhaled, the first symptoms appear after 4-8 hours. Inhaling the gas for 60-90 minutes is not poisonous, but sensitive people may experience mild poisoning. Inhaling one milligram per liter for 5 minutes leads to a 70% death rate.
Phosgene affects taste buds and the olfactory nerve, after which a person’s sense of smell becomes dull. Symptoms: pulmonary edema, but at particularly high concentrations it does not occur; at high concentrations a person inhales the gas, falls sharply to the ground, convulsions begin and the face turns dark blue, death quickly occurs. Due to the volatility of phosgene, it was used as a military weapon.
Chlorine– a simple gas, yellowish in color, has a metallic taste. Chlorine is used in industry, science and everyday life; it was used by Germany in the First World War in 1915. If it enters the lungs, it causes burns to lung tissue; in higher concentrations it causes suffocation.
Potassium cyanide
Potassium cyanide is a colorless crystal, similar to sugar with the smell of almonds. A very powerful poison; if it enters the gastrointestinal tract, the lethal dose for an adult is 1 mg/kg. Causes convulsions, difficulty breathing and death within minutes.
Strychnine– white, odorless powder. For poisoning, a small amount is enough; the poison can be ingested by breathing, touching or eating. Causes seizures, difficulty breathing, and brain death approximately 30 minutes after injury.
The video shows dangerous animal poisons, their symptoms and effects on the human body.
Esters are clear liquids, often with a pleasant fruity odor. They are neutral and very stable, but can hydrolyze when heated in the presence of strong acids or bases. They are less polar than the same alcohol as a solvent. Esters have extremely good solubility for polar substances; With increasing length of the carbon chain in alcohol and acid groups, solubility with respect to polar products decreases, but increases with respect to less polar substances. Lower esters are partially soluble in water. The most important solvents in the group of esters for the paint and varnish industry are acetates. Formates are used to a lesser extent because they have a stronger effect on living organisms and are more easily hydrolyzed. Propionates, butyrates and isobutyrates are less important as they have a strong fruity odor. Also of great importance are some esters of glycolic and lactic acids, as well as dimethyl esters of mixtures of dicarboxylic acids.
Methyl formate is a colorless, water-soluble liquid. It dissolves nitrocellulose, cellulose acetate, oils and fatty acids. Ethyl formate - partially miscible with water. It dissolves nitrocellulose, cellulose acetate and many resins. Butyl formate - slightly soluble in water. It dissolves nitrocellulose, fats, oils, many polymers and chlorinated rubber. However, it does not dissolve cellulose acetate. Isobutyl formate has solvent properties similar to butyl formate. It is part of commercially produced paint solvents. Methyl acetate is partially miscible with water and mixes easily with many organic solvents. For example, with vinegar essence, everyone knows where to buy it. It dissolves well cellulose esters and ethers, rosin, polyurea, melamine and phenol-formaldehyde resins, polyvinyl acetate, alkyd, ketone and other resins. It will not dissolve shellac, dammar resin, copal or polyvinyl chloride. Methyl acetate is used as a highly volatile solvent to reduce the viscosity of paints (alone or mixed with alcohols or other esters), as an acetone substitute in adhesives, and as a softener (plasticizer) for hard shoe uppers in the footwear industry.
Ethyl acetate is a colorless neutral liquid that has limited miscibility with water and has a pleasant fruity odor. It has good dissolving ability towards nitrocellulose, cellulose ethers, chlorinated rubber, polyvinyl acetate, vinyl chloride copolymers, polyacrylates, polystyrene, fats, oils, many natural and synthetic resins (alkyd, saturated polyester, ketone resins). However, cellulose acetate is only soluble in the presence of small amounts of ethanol. Does not dissolve polyvinyl chloride. Ethyl acetates are very important chemical solvents for fast-drying paints (such as nitrocellulose-based wood paints).
