What is the difference between iodophenol and iodine wine, you can think of iodophenol as iodine

Iodophenol is used to treat toothache, while iodine is used to disinfect. Because phenols are extremely corrosive, if they are used as iodine wine, they can easily cause ulcers. Moreover, iodophenol** dental hyperesthesia has certain limitations, and it is only suitable for posterior occlusal surfaces, which is inconvenient for tooth neck allergy and adjacent sensitive areas.

Because iodophenol is strongly corrosive to the soft tissues of the oral cavity and is a liquid drug, the gums are easily burned or scalded, therefore, patients cannot use it themselves; Iodine wine should not be used in excess, otherwise it will cause iodine poisoning or wound corrosion. No matter what iodine drugs, red mercury should not be mixed, otherwise it will cause severe corrosion.

Iodine wine is made by dissolving iodine and potassium iodide in an alcohol solution. Iodine is a solid, and potassium iodide helps in the dissolution of iodine in alcohol. Commercially available iodine has a concentration of 2.

Iodine wine - the principle of disinfection.

The principle of iodine (alcohol) disinfection:

Iodine (alcohol) is the most commonly used disinfectant, with 75% alcohol used for sterilization. Different concentrations of alcohol are made from high concentration (95%) alcohol diluted with distilled water.

The reason why alcohol can be disinfected is because alcohol can absorb the moisture of bacterial proteins, dehydrate and denature, and solidify, so as to achieve the purpose of killing bacteria. If a high concentration of alcohol is used, the bacterial protein is dehydrated too quickly, so that the protein on the surface of the bacteria first denatures and solidifies, forming a strong envelope, but the alcohol cannot penetrate well into the bacteria, so as to affect its bactericidal ability. 75% alcohol is similar to the osmotic pressure of bacteria, which can gradually and continuously infiltrate into the inside of the bacteria before the protein on the surface of the bacteria is not denatured, so that all the proteins of the bacteria are dehydrated, denatured and coagulated, and finally kill the bacteria, when the alcohol concentration is lower than 75%, due to the reduction of permeability, it will also affect the bactericidal ability.

It can be seen that the strength of alcohol sterilization and disinfection ability is directly related to its concentration, too high or too low, the best effect is that 75% alcohol is very volatile, so after the disinfection alcohol is prepared, it should be immediately placed in a bottle with good sealing performance to seal and preserve, and set aside, so as not to reduce the concentration due to volatilization and affect the sterilization effect.

Iodine wine is composed of iodine and potassium iodide.

The concentration of iodine tincture generally varies with the nature of the drug or medicinal material, unless otherwise specified, the iodine tincture containing highly toxic drugs is equivalent to 10 grams per 100 ml of the original drug or medicinal materials, and the other iodine tincture is equivalent to 20 grams of drugs or medicinal materials per 100 milliliters, and the active ingredients of iodine tincture containing highly toxic drugs should be adjusted according to the content or potency of the semi-finished product to meet the requirements of each iodine tincture.

Because it has the active gene of oxidation and destruction of pathogen plasma protein, and combines with the amino group of the protein to denature and precipitate, it has a strong bactericidal effect, and also has a killing effect on fungi, viruses and amoeba protozoa, and even the most difficult to kill bacterial spores, iodine tincture can play a disinfecting role.

Method] take potassium iodide, add 20ml of water to dissolve, add iodine and ethanol, stir to dissolve, and then add an appropriate amount of water.

into 1000ml, that is.

Properties] This product is a reddish-brown clear liquid; It has a special odor of iodine and ethanol.

Identification] (1) take 1 drop of this product and drop it into a mixture of 1ml of starch indicator solution and 10ml of water, that is, dark blue.

Hue. (2) take 5ml of this product, evaporate it on a water bath, slowly burn it, so that the free iodine is completely volatilized, and the residue is dissolved in water, and the identification reaction of potassium salt and iodide is displayed (Appendix).

Content determination] take 10ml of this product for iodine precision, place it in a stopper flask, add 1 drop of acetic acid, and use thiosulfur.

Sodium acid titration solution (titrate until the solution is colorless. Per 1 ml of sodium thiosulfate titration solution (equivalent to 12

69mg of I.

Take the above titrated solution of potassium iodide, add 2ml of acetic acid and eosin sodium indicator solution, and titrate the solution with silver nitrate.

titration until the precipitate changes from yellow to rose-red; The silver nitrate titration solution () will be consumed.

Volume (ml) minus the volume (ml) of sodium thiosulfate titration solution consumed above (ml). Per 1 ml of silver nitrate titration solution.

Equivalent to ki.

If you want to do the question, it can only be as follows.

Iodine is 2% by mass ratio i:ki=137:(137+39).

So the mass fraction of potassium iodide is 2% (137+39) 137=

Then the mass fraction of alcohol is.

It is an ethanol solution of iodine I2. Potassium iodide is used during preparation to increase the solubility of iodine elements in ethanol solution. So iodine wine contains the following substances: iodine, potassium iodide, ethanol, distilled water.

Iodine wine is made by dissolving iodine and potassium iodide in an alcohol solution.

1% iodine wine can be applied to the mucous membrane, and 2% iodine wine is used for general disinfection and infection, such as small boils; A 5% iodine wine is used for sterilization before surgery or injections. For infection and disinfection.
