Volatilization of 3,3-dimethyl-2-butanone from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.2X10-4 atm-cu m/mole(SRC), derived from its vapor pressure, 31.5 mm Hg(4), and water solubility, 19,000 mg/L(5). However, NIST makes no warranties to that effect, and NIST Is mark weinstein related to Harvey Weinstein? Copyright © 2020 Multiply Media, LLC. I’m Ben Valsler, thanks for listening. Butanone’s use as a solvent is why it’s one of the most important commercially produced ketones –right up there with acetone, with which it shares many properties. Articles of 2-Butanone are included as well.

Rather than acting as a genuine adhesive – binding to the surface of the material – butanone is effectively a chemical welding agent.

For a group assignment, some of the boys in my class – around 11–12 years old – demonstrated how you could make different kinds of glue by dissolving expanded polystyrene packing peanuts into butanone.

2-Butanone, also known as methyl ethyl ketone (MEK), is a colorless liquid with a sweet, but sharp odor. For this reason it finds use in the manufacture of plastics, textiles, in the production of paraffin wax, and in household products such as lacquer, varnishes, paint remover, a denaturing agent for denatured alcohol, glues, and as a cleaning agent.
Extensive use in industry, and the exposure that comes with that, has allowed us to collect comprehensive data on its interaction with the human body. The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. Luckily, it’s mostly broken down quite quickly by pathways like the cytochrome p450 monooxygenase system, and the rest is excreted in urine. Select a region with data to zoom. jcamp-plot.js.

Until then, you can get in touch by emailing firstname.lastname@example.org or tweeting @chemistryworld, and you can find all of our previous podcasts, including the Chemistry World Book Club, at chemistryworld.com/podcasts. Butanone, also called methyl ethyl ketone (MEK) and Butan-2-one, is a chemical compound which is commonly used as a solvent in the manufacture of many products. The idea was to teach science in English so that the pupils became familiar with the language of science, as well as the facts and processes.

The plastic surfaces dissolve on contact, and then as the ‘glue’ evaporates away, they repolymerise into a new, bonded structure.

It can kill bacterial spores on surgical instruments and has even been used as a synthetic flavouring agent. It can irritate mucous membranes such as the lungs, but serious adverse effects only seem to occur after unusually large doses. You might be more familiar with butanone as the solvent that makes the ink flow in the dry-erase marker pens we use to write on whiteboards, and gives them their distinctive sweet, sharp smell.
But it does enhance the negative effects of certain other substances, for example it increases the neurotoxicity of hexane and the liver and kidney toxicity of haloalkane solvents.
