Is alcohol an organic solvent?

Organic solvent is an organic compound that can dissolve some water-insoluble substances (such as oil, wax, resin, rubber, dye, etc.). ). Its characteristic is that it is liquid at normal temperature and pressure and has high volatility. In the process of dissolution, the properties of solute and solvent have not changed. There are many kinds of organic solvents, which can be divided into 10 according to their chemical structures: ① aromatic hydrocarbons: benzene, toluene, xylene, etc. ② Aliphatic hydrocarbons: pentane, hexane, octane, etc. ③ alicyclic hydrocarbons: cyclohexane, cyclohexanone, toluene cyclohexanone, etc. ④ Halogenated hydrocarbons: chlorobenzene, dichlorobenzene, dichloromethane, etc. ⑤ Alcohols: methanol, ethanol, isopropanol, etc. ⑥ Ethers: ether, propylene oxide, etc. ⑦ Esters: methyl acetate, ethyl acetate and n-propyl acetate. 8 ketones: acetone, methyl butanone, methyl isobutyl ketone, etc. 9 Diol derivatives: ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, etc. Attending others: acetonitrile, pyridine, phenol, etc.

Alcohol is one of the common teratogens in daily life. When parents drink too much to cause chronic alcoholism, it can weaken the vitality of sperm or eggs or cause abnormal development, thus affecting the development of fertilized eggs and embryos. The effects of alcohol on the fetus are as follows:

1, alcoholism syndrome

If pregnant women drink alcohol all the time during pregnancy, harmful components in alcohol can reach the fetus through the placenta, leading to fetal development disorder and abnormal growth and development after birth, such as central nervous system dysfunction and abnormal facial features. This phenomenon is called "alcoholism syndrome".

The extent to which alcohol harms the fetus depends on the amount of alcohol consumed by pregnant women. Recent studies have proved that it can not only lead to facial ugliness, but also lead to heart defects, hand and foot deformities and mental retardation.

2. Congenital infant diseases

Here refers to couples suffering from chronic alcoholism caused by alcoholism, or babies who are pregnant in the same room after drinking on Sunday holidays. This is a special disease.

Because alcohol damages germ cells, the quality of fertilized eggs is not perfect. This kind of baby is worse than normal baby in both physical strength and intelligence. Stunting and underweight; There are often facial deformities such as small head and small eye crack, and the face is ugly; Abnormal joints of limbs; Heart or other visceral malformations.

Therefore, pregnant women and their husbands should resolutely put an end to drinking if they want to have a healthy and intelligent offspring.

What are the characteristics of medicinal alcohol? Medicinal alcohol (ethanol) is an essential medicine for medical units and family medicine boxes. It is worth noting that different uses require different concentrations. 95% alcohol medical units are often used in alcohol lamps and alcohol stoves, which are used to prepare laboratory reagents or pharmaceutical preparations and heat them after ignition, and can also use their flames to temporarily disinfect small medical devices. 70% ~ 75% alcohol can be used for disinfection, including skin disinfection, medical instrument disinfection, iodine removal and so on. Because alcohol is irritating, 75% alcohol can be used for skin disinfection, not for mucous membranes and large wounds. 40% ~ 50% alcohol is used to prevent bedsores. Nurses can pour a small amount of 40% ~ 50% alcohol on their hands and massage the patient's compressed parts evenly to promote local blood circulation and prevent the formation of bedsores. 25% ~ 50% alcohol is used for physical antipyretic. The specific method is: the nurse soaks the gauze or soft towel with alcohol, wrings it until it is half dry, and gently wipes the patient's neck, chest, armpits, limbs, hands and feet. The alcohol concentration used for rubbing bath should not be too high, otherwise the large-scale use of high-concentration alcohol will stimulate the skin and absorb a lot of water from the epidermis.
