Astronauts have described some unusual scents in space, which is not surprising considering the chemistry there is far different from that on Earth. So what does space smell like, and what are the cosmic sources of these odors? Space is an airless vacuum, so technically, you can't smell any...
So what is methanol, and how does it make people sick? Methanol versus ethanol Methanolis analcohol, like the familiarethanolwe consume in alcoholic beverages. Likeethanol, methanol is a colorless, flammable liquid. It has a smell similar to ethanol as well. But the two have different chemical...
The ‘freshly cut grass’ smell isn’t from a single chemical. Grasses release a host of different volatile chemicals when they are cut, called Green Leaf Volatiles (GLV). Some of these chemicals are acetone, formaldehyde and methanol, which constitute almost 60% of emissions when grass is c...

In biodiesel production, oils and fats are heated with an alcohol like methanol and a catalyst to create biodiesel and crude glycerine. This process, called transesterification, transforms triglyceride esters into another type of ester – fatty acid methyl esters, which is also called biodiesel. And...
Some companies, however, have taken the chemistry a step further and offer concentrated extracts that are produced using harsh solvents such as acetone or methanol. Although some studies suggest that extracts are mostly void of toxic effects, others have raised the idea that perhaps extracts are ...
It's killing me. At least psychologically. I'm afraid it might be something toxic like methanol. I guess for you to be able to tell what the fumes might consist of you'd need to know some more details. The brew is made of sugar and yeast, sometimes it's distilled without even being...
At room temperature, Undecenoic acid is a colorless, glossy liquid with a unique fruity odor, or a colorless deliquescent solid with a putrid smell. It is slightly soluble in water and soluble in ethanol and ether. It is low in toxicity and has mild irritant properties. ...
converts the sugars present in grapes (which make up around 30% of the grape mass) into alcohol and carbon dioxide (the remaining 70%). While this process contributes to the flavor and taste of wine, it does not impact its smell, as smell is solely perceived through the olfactory senses...
