Q:What is acrylic acid？
A:ainer, violent rupture may occur. The inhibitor (usually hydroquinone) greatly reduces the tendency to polymerize.
Acrylic acid is an organic molecule and the simplest of the unsaturated acids. At room temperature, acrylic acid is a liquid and has a characteristic acid and tart aroma. It is corrosive in liquid and vapor forms. Acrylic acid is used mainly in the formation of polymers. Its uses include plastics, coatings, adhesives, elastomers, paints, and polishes. Additionally, acrylic acid is used in the production of hygienic medical products, detergents, and wastewater treatment chemicals. The low toxicity of acrylic acid is due to its corrosive nature. Studies have suggested that acrylic acid poses some reproductive hazards.
Q:What is acrylic acid used for?
A:The acrylic acid market has grown over the years, as usage of this chemical has increased in various sectors, ranging from cosmetic products, like acrylic nail polish, to use chemical industries. Acrylic acid usage has also run into various controversies as health agencies in US have scrutinized its usage in various products. Traditionally, acrylic acid has been used as a raw material in the industrial preparation of acrylic esters. These acrylic esters like methyl acrylate, ethyl acrylate etc., have been used for preparation of solvent-based resins, however, due to environmental concerns, their production was stopped. Further, water-based acrylics were developed that found extensive use in home coatings, and in various other products, like paintings, paper, adhesives, and polishes. With further research, a class of compounds known as polyacrylates were developed with the help of acrylic acids, that are used in making thickeners and dispersants. Since the last decade, acrylic use has become extremely popular in two specific areas―the production of Superabsorbent Polymers (SAPs) and detergent polymers. These unique SAPs have been reported to contribute nearly 30% of the world’s acrylic acid market consumption.
Basically, SAPs have a unique feature to absorb and at the same time retain moisture 100 times more than their own weight. This has made them an integral part in the production of baby diapers, female hygiene products, and in adult incontinence products. Summarized briefly, acrylic acid is a chemical intermediate that is required for preparation of polymers, textiles, ink industries, consumer products, plastics, surfactants chelating agents, water-based coating, and often in food packaging industries, with strict guidelines from health agencies.
adhesive, any substance that is capable of holding materials together in a functional manner by surface attachment that resists separation. “Adhesive” as a general term includes cement, mucilage, glue, and paste—terms that are often used interchangeably for any organic material that forms an adhesive bond.
Q:Is acrylic acid harmful?
A:The substance is corrosive to the eyes and skin. Corrosive on ingestion. The vapour is severely irritating to the eyes and respiratory tract. A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C , on spraying or dispersing much faster.
Q:How do you store acrylic acid?
A:Acrylic acid should be stored in a detached, cool, well-ventilated, non-combustible place, and its containers should be protected against physical damage. Acrylic acid can be stored only in vessels lined with glass, stainless steel, aluminum, or polyethylene. In order to inhibit polymerization during transport and storage, 200 ppm MeHQ (the monomethyl ether of hydroquinone) is commonly added to acrylic acid by the manufacturer. The presence of oxygen is required for the inhibitor to be effective. A major concern during the storage of acrylic acid is the avoidance of elevated temperatures as well as freezing, since both can lead to a failure of the inhibitor system. Ideally acrylic acid should be stored within a temperature range of 15 to 25 deg C.
Q:Is acrylic acid harmful to the environment?
A:Acute toxic effects may include the death of animals, birds, or fish, and death or low growth rate in plants. Acute (short term) effects are seen two to four days after animals or plants come in contact with a toxic chemical substance. Acrylic acid has slight acute toxicity to aquatic life and high toxicity to birds.
