What is banana oil?
I. Meaning
Banana oil, also known as Tianna Water, is a colorless, transparent and volatile liquid. Banana has a strong smell, is slightly soluble in water and can be dissolved in various organic solutions. It belongs to flammable substances and is mainly used as solvent and diluent for paint. What we come into contact with is that banana oil is used as food additive, and a small amount is used in food, which can play the role of food preservative. At the same time, banana oil is also an important raw material for pharmaceutical industry.
Second, nature.
Banana oil is esterified by acetic acid and isoamyl alcohol separated from fusel oil under the catalysis of sulfuric acid. Isoamyl acetate exists in cocoa beans and bananas. In industry, pentanol separated from fusel oil is used as raw material. Isoamyl alcohol and sulfuric acid are added into glacial acetic acid, and then heated and refluxed. When the top temperature of fractionator reaches 132℃,
It will be completely esterified. After cooling, washing with water, neutralizing with 10% NaOH solution, washing with water until neutral, drying with anhydrous calcium chloride, distilling, and collecting 138 ~ 143℃ fraction to obtain the product. Third, the harm to health.
It has a * * effect on eyes and mucous membranes, and high concentration inhalation will cause damage to the central nervous system, even liver and kidney. Acute poisoning may include acute conjunctivitis, pharyngitis, bronchopneumonia and pulmonary edema.
Long-term contact, tears, cough, dry throat, fatigue and other symptoms, severe cases accompanied by headache, nausea, vomiting, chest tightness, palpitations, loss of appetite and so on. Can cause chapped skin, dermatitis or eczema; It can cause anemia and eosinophilia. Fourth, the storage method
Store in a cool and ventilated warehouse. Stay away from fire and heat sources. The reservoir temperature should not exceed 30℃. Should be stored separately from oxidant, acid and halogen, and should not be mixed. Adopt explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are easy to generate sparks. The storage area should be equipped with emergency response equipment for leakage and suitable accommodation materials.
Verb (short for verb) price
As far as the price is concerned, I think everyone should be more concerned. As for the specific price of banana oil, in fact, I can't give you a standard and accurate answer because there are many factors that affect the price change. But according to my recent understanding of the market, the price in banana oil is not very expensive, and the general market price is almost 50 ~ 60 yuan a barrel. Of course, according to different brands and regions, the price may be more or less different. But it shouldn't be very big. If you want to wholesale directly from the factory, the general wholesale price is about 8 ~ 10 yuan per catty, which is one kilogram. This price is for reference only.
