The difference and role of sublimation sulfur and sulfur in the popular science chapter

Sulfur gasifies into a gas at high temperatures, called sublimation
.

If the gasified sulfur is taken away before it is burned, it cannot continue to burn below the ignition point temperature (about 250 ° C), and when it is cooled, it will re-condense into a solid, that is, the sulfur (S) content shall not be less than 98.
0%, which is called sublimation sulfur
.

Sublimation sulfur is a yellow crystalline powder with a slight odor and is almost insoluble
in water or ethanol.

Chinese Name: Sublimation Sulfur Foreign Name: Sublimed Sulfur Chemical Formula: SCAS Registration Number: 7704-34-9 Water Solubility: Insoluble in Water, Soluble in Carbon Disulfide View: Yellow Powder Gas: Slightly Odorous Use: Insecticide [Storage] Sealed

【Preparation】Sulfur ointment pharmaceutical grade sublimation sulfur API Chinese medicine quasi-word for hospitals to use sublimation sulfur has the effect of
killing bacteria, fungi and scabies.

Sublimation sulfur is a bactericidal, fungicidal and scabies killing effect, sublimated sulfur can reduce sebum, and has the effect of keratinization and keratin solvents; Sublimation of sulfur sterilization viability is the result of
the transformation of epidermal cells or certain microorganisms into pentasulfonic acid.

Sublimation of sulfur sterilization viability is the result of
the transformation of epidermal cells or certain microorganisms into pentasulfonic acid.

The main indications for sublimation sulfur are sitting sores, seborrheic dermatitis, rosacea, pityriasis simplex, scabies, subacute and chronic eczema, neurodermatitis, psoriasis, tinea phytophyllum, tinea capitis, tinea pedis and so on

.

The drug interaction of sublimation sulfur is the preparation and storage of sulfur preparations, do not contact with iron products to prevent discoloration, when the lesion site is washed and rinsed with soap and other cleaning agents, it can be dried and then applied to the drug, if the patient needs to use this drug, it is recommended to go to a regular general hospital for treatment
.

How to use sublimation sulfur powder for skin sublimation sulfur powder can generally be applied to the skin
.

Sublimation sulfur powder kills bacteria, fungi and scabies, but also reduces sebum, promotes keratinization and acts as a keratin solvent
.

The sublimation sulfur powder bactericidal activity is the epidermal cells that can convert microorganisms into pentasulfonic acid
.

It is mainly suitable for seborrheic dermatitis, tinea manoeuvres and neurodermatitis
.

When preparing and storing, do not touch iron products to prevent discoloration
.

It is recommended to wash the affected area before applying the drug
.

The national medicine quasi-word sublimation sulfur API, in line with the pharmacopoeia standards Finally, give you a popular science about the difference between sublimated sulfur and sulfur: 1, what is the difference between sulfur and sublimation sulfur Due to different processing methods, it is divided into three kinds
: sublimation sulfur, sedimentation sulfur and refined sulfur.

Sublimation sulfur: for sulfur yellow after sublimation into refined sulfur: for the sublimation of sulfur and ammonia water, remove impurities of the sedimentation sulfur: for refined sulfur and calcined lime action, hydrochloric acid decomposition
.

The particles of sedimentation sulfur are the finest and are easy to make into delicate and easy to disperse finished products
.

When preparing drugs, the specific use of sedimentary sulfur or sublimation sulfur depends on the requirements of the formula and dosage form, and there are requirements in the general pharmacopoeia
.

2, the chemical properties of sulfur is what sulfur chemical properties are more active, can be combined with oxygen, hydrogen, halogen (except iodine), metals and most other elements to form ionic compounds or covalent compounds
.

Sulfur elemental is both oxidizing and reducing
.

For example, sulfur and iron co-heat to form ferrous sulfide, carbon disulfide at high temperature with carbon, sulfur hexafluoride with fluoride at room temperature, and S2Cl2
with chlorination when heated.

Sulfur is mainly used in the industry to make sulfuric acid, vulcanized rubber, matches, sulfides and so
on.

It is used agriculturally as an insecticide, such as a lime sulfur mixture, and also in the manufacture of medicine, such as sulfur ointment
.

Ancient people have known about natural sulfur
.

Sulfur exists in nature in a free and synthetic state, and the compound states mainly include sulfides and sulfates
.

The abundance in the earth's crust is 0.
048%.


It is produced from natural sulfur ore or is made by mixing pyrite and coke and burning them in limited air
.

Pharmaceutical grade sublimation sulfur APIs comply with pharmacopeia standards
