Harm of tetrahydrofuran to humans, harm of tetrahydrofuran to plants

Long-term exposure to THFRAN can cause great damage to the blood and cause chronic poisoning. Causes neurasthenic syndrome.

Do you want to ask what are the dangers of THF to plants? The hazards of this organic compound to plants are as follows:

1. Tetrahydrofuran is volatile in the air, and when the concentration is higher than that of the orange, it is easy to cause dehydration of plant leaves, causing plant withering and dying.

2. Drinking water contaminated with THF can affect the growth and development of plants, and even cause plant death.

3. The use of pesticides containing tetrahydrofuran in large quantities will lead to a large increase in the concentration of THF in farmland soil, thereby affecting the growth and quality of crops.

Obviously toxic. Organic solvents are toxic. Long-term exposure to THC may cause infertility in women.

Furan is toxic for reproduction, but it is not very toxic, so there should be no problem with paying attention.

Tetrahydrofuran.

Tetrahydrofuran

Don't] oxacyclopentane.

Uses] Tetrahydrofuran has the characteristics of low toxicity, low boiling point, good fluidity, etc., is an important organic synthesis raw material and excellent solvent, with a wide range of uses, tetrahydrofuran has good solubility to many organic substances, it can dissolve all organic compounds except polyethylene, polypropylene and fluorine resin, especially for polyvinyl chloride, polyvinylidene chloride, and cataniline has a good solubility, is widely used as a reactive solvent, known as "universal solvent". As a commonly used solvent, tetrahydrofuran has been widely used in surface coatings, protective coatings, inks, extractants and artificial leather surface treatment, tetrahydrofuran is an important raw material for the production of polytetramethylene ether glycol (PTMEG), and is also the main solvent in the pharmaceutical industry.
