Furfural is used to make other furan derivatives, such as furoic acid, via oxidation, [30] and furan itself via palladium catalyzed vapor phase decarbonylation. [4] There is a good market for value added chemicals that can be obtained from furfural. [20]
Flatulence can be a problem for some dogs, which may be diet-related or a sign of gastrointestinal disease. This, in fact, may be the most commonly noticed source of odor from dogs fed cereal-based dog foods. Skunks and dogs often have aggressive encounters and a dog may be sprayed by a skunk. This results in an over-powering musky acrid odor ...
Dogs with elongated noses perform better than dogs with a flat noses. Additionally, larger dogs have a better sense of smell than smaller dogs. [7] A dog's nose is significantly colder than their body temperature. This makes it more sensitive to thermal radiation. Dogs can thus detect even weak levels of warmth. [8]
Body odor, however, can be used as an indication for disease. For example, typically, human urine contains 95% water, [41] however, for a person with an abnormal amount of blood sugar, their urine becomes more concentrated with glucose. [42] Therefore, if a person's body odor or urine smells unusually fruity or sweet, that can be a sign of ...
A dogs acuity to a scent group is so refined they are able to discriminate humans by odour [7] and can even match certain scents to specific body parts of an individual. [8] Scent discrimination is most proficient while a human odour is fresh and becomes more difficult once an odour starts to fade.
Sweat and body odor are typically thought to go hand in hand, but experts say it's a little more complicated than that. Sweat alone doesn't have a smell, according to Harvard Health.
Hydroxymethylfurfural (HMF), also known as 5-(hydroxymethyl)furfural, is an organic compound formed by the dehydration of reducing sugars. [4] [5] It is a white low-melting solid (although commercial samples are often yellow) which is highly soluble in both water and organic solvents.
The primary use of furfuryl alcohol is as a monomer for the synthesis of furan resins. [4] [8] These polymers are used in thermoset polymer matrix composites, cements, adhesives, coatings and casting/foundry resins. Polymerization involves an acid-catalyzed polycondensation, usually giving a black cross-linked product. [9]
