| SYMPTOMS | FIRST AID | ||
| Inhalation | Eye and nasal irritation and lacrimation | First, leave the contaminated area; take deep breaths of fresh air. Call a doctor IMMEDIATELY and be ready to take the victim to the hospital, even if no symptoms develop. | |
| Skin | May burn skin or eyes upon short contact. | Immediately rinse the affected skin with water, while removing and isolating all contaminated clothing. contact a hospital or poison control center, even if there are no symptoms | |
| Eyes | Redness. Pain. | Rinse the victim's eyes with water or ordinary saline solution for 20-30 minutes, while calling a hospital or a toxicology center. | |
| Ingestion | May cause severe damage to the gastrointestinal tract. | Do not induce vomiting，aggressive chemicals destroy the membranes of the mouth, throat and esophagus and, in addition, have a high risk of entering the victim's lungs during vomiting, which increases medical problems. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical, and IMMEDIATELY call the hospital or toxicology center. | |
There are many production methods of acrylic acid, including chloroethanol method, cyanoethanol method, high pressure Rape method, enone method, acrylonitrile hydrolysis method, etc. At present, acrylic acid adopts propylene two-step oxidation method.Propylene is first oxidized to acrolein, and then further catalyzed to acrylic acid
Frequently Asked Questions
Q: What is Ice Crystal High Purity Acrylic Acid?
A: Basic information of ice crystal high-purity acrylic acid The boiling point of acrylic acid is 141°C. Acrylic acid is an important organic synthetic raw material and synthetic resin monomer, and is a vinyl monomer with a very fast polymerization rate. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group and a carboxyl group. Pure acrylic acid is a clear, colorless liquid with a characteristic pungent odour. It is miscible with water, alcohols, ethers and chloroform and is prepared from propylene obtained from refineries.
Q:Acrylic acid production process
A: There are many ways to produce acrylic acid, such as chlorohydrin method, cyanohydrin method, high-pressure rapey method, enone method, acrylonitrile hydrolysis method, etc. At present, acrylic acid in my country adopts two-step oxidation method of propylene. Propylene is first oxidized to acrolein, and further catalyzed to acrylic acid
Q: The main function of acrylic acid
A: The most important uses are water-absorbent resins and acrylics. In addition, it can also be used as a water reducing agent in concrete.
(1) Important organic synthetic raw materials and synthetic resin monomers, mainly used to manufacture methyl acrylate, ethyl ester, butyl ester, hydroxypropyl ester, hydroxyethyl ester and other acrylates.
(2) Acrylic acid and acrylates and monomers (amides, acrylonitrile, vinyl, styrene, butadiene and maleic anhydride) are homopolymerized or copolymerized, and their polymers are used to produce plastics, coatings, and adhesives .Floor polish and paint.Pharmaceutical.Textile.Water treatment (water thickener)
(3) The copolymer of acrylic acid and ethyl acrylate can be used as a thickening agent for crude oil extraction in oil fields, which can increase the amount of extraction.
Ice crystal acrylic is mainly used as superabsorbent resin, mainly used in various court surface materials, and also used in the field of hygiene products (diapers)
