Eksempler på bruk av FORMALDEHYDE i en setning

• Aldehyde molecules have a central carbon atom that is connected by a double bond to oxygen, a single bond to hydrogen and another single bond to a third substituent, which is carbon or, in the case of formaldehyde, hydrogen.
• It can be thought of chemically as the double acyl chloride analog of carbonic acid, or structurally as formaldehyde with the hydrogen atoms replaced by chlorine atoms.
• Formaldehyde is classified as a carcinogen and can cause respiratory and skin irritation upon exposure.
• Genetic evidence from comparisons of multiple organisms showed that a glutathione-dependent formaldehyde dehydrogenase, identical to a class III alcohol dehydrogenase (ADH-3/ADH5), is presumed to be the ancestral enzyme for the entire ADH family.
• It is a controversial event, mainly for the exhibits, such as The Physical Impossibility of Death in the Mind of Someone Living – a shark in formaldehyde by Damien Hirst – and My Bed, a dishevelled bed by Tracey Emin.
• Key works include Hirst's The Physical Impossibility of Death in the Mind of Someone Living, a shark preserved in formaldehyde in a vitrine, and Emin's My Bed, a dishevelled double bed surrounded by detritus.
• A phenol formaldehyde resin, it can be worked with files, grinders, and cutters, and polished to a fine sheen.
• 1,3,5-trioxane, a trimer of formaldehyde used as fuel and in plastics manufacturing, and also as a solid fuel tablet when combined with hexamine.
• The butanediol is derived from condensation of acetylene with formaldehyde followed by hydrogenation.
• It is composed of a mixture of formaldehyde and concentrated sulfuric acid, which is dripped onto the substance being tested.
• 3 million for The Golden Calf, an animal with 18-carat gold horns and hooves, preserved in formaldehyde.
• He would demonstrate the device by building a noxious fire fueled by tar, sulfur, formaldehyde, and manure inside an enclosed tent.
• From 1970 to 1972, NEPACCO was primarily involved in the production of hexachlorophene (3), an antibacterial agent used in soap, toothpaste, and common household disinfectants, from 2,4,5-trichlorophenol (1) and formaldehyde (2).
• February 5 – Leo Baekeland announces the creation of the early plastic Bakelite, a hard thermosetting phenol formaldehyde resin, to the American Chemical Society.
• Phenol formaldehyde resins (PF) (phenolic resins or phenoplasts) are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde.
• Instead, molecules such as carbon dioxide, carbon monoxide, formaldehyde, ammonia, or acetonitrile are typically used to determine the mass of a cloud.
• This interpretation challenged the century-old Adolf von Baeyer theory of photochemical reduction of CO adsorbed on chlorophyll which had guided decades of effort by Richard Willstätter, Arthur Stoll, and many others in vain searches for formaldehyde.
• The Rosetta mission found carbon monoxide, carbon dioxide, ammonia, methane and methanol in the Coma of Comet 67P, as well as small amounts of formaldehyde, hydrogen sulfide, hydrogen cyanide, sulfur dioxide and carbon disulfide.
• Less extensive dissection of plants and smaller animals preserved in a formaldehyde solution is typically carried out or demonstrated in biology and natural science classes in middle school and high school, while extensive dissections of cadavers of adults and children, both fresh and preserved are carried out by medical students in medical schools as a part of the teaching in subjects such as anatomy, pathology and forensic medicine.
• Volatile organic compounds (VOCs) – Organic compounds which typically have a boiling point less than or equal to 250 °C; for example chlorofluorocarbons (CFCs) and formaldehyde.
• Paul Berg's doctorate paper is now known as the conversion of formic acid, formaldehyde and methanol to fully reduced states of methyl groups in methionine.
• The first, a polio vaccine developed by Jonas Salk, is an inactivated poliovirus vaccine (IPV), consisting of a mixture of three wild, virulent strains of poliovirus, grown in a type of monkey kidney tissue culture (Vero cell line), and made noninfectious by formaldehyde treatment.
• Colistimethate sodium is a prodrug; it is produced by the reaction of colistin with formaldehyde and sodium bisulfite, which leads to the addition of a sulfomethyl group to the primary amines of colistin.
• The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use.
• A structural resin, typically RF curing melamine formaldehyde (MF) or PF resin, is applied to the joint between successive boards and cured under end pressure using a continuous RF curing system.
