What is phenolic water?
Phenolic (or more broadly, non-HDS) water typically contains heat stable salts (HSSs) and HCN, although phenols and caustic may also be present, depending on how the water has been used in the refinery. It contains organic and inorganic impurities derived from HSS precursors, especially derived from HCN.
What does phenolic mean in biology?
Phenolic is an adjective and a substantive (noun) that may apply to : Phenol (or carbolic acid), a colorless crystalline solid and aromatic compound. Phenols, a class of chemical compounds that include phenol.
What is a phenolic solution?
Phenolic compounds were among the earliest germicides used in Healthcare after World War II. They were introduced as an alternative to chlorine. Many phenolic products are used for the decontamination of environmental surfaces and some (e.g. triclosan and chloroxylenol) are among the more commonly used antiseptics.
How do you describe phenolic?
Phenolic flavors and aromas are often described as clove-like, medicinal, smoky, or “band-aid” and are considered off-flavors in most beer styles.
What is phenolic and non phenolic?
Non-phenolic water contains almost exclusively NH3, H2S, and possibly a trace of CO2. Phenolic (or more broadly, non-HDS) water typically contains heat stable salts (HSSs), HCN, phenols,and caustic.
Is phenolic waterproof?
The plywood sheets are manufactured to a high standard, making them resistant to corrosion and moisture. The coating of the wood is phenolic resin and it is this coating that makes it waterproof.
What are phenolic disinfectants?
Phenolic compounds used as antiseptics or disinfectants include pure phenol and substitution products with halogens and alkyl groups. They act to denature and coagulate proteins and are general protoplasmic poisons. Phenol (carbolic acid) is one of the oldest antiseptic agents.
What are phenolic structures?
Phenolic compounds are defined as natural metabolites arising biogenetically from either the shikimate/phenylpropanoid pathway, which directly provides phenylpropanoids. Their structure consists of an aromatic ring, containing one or more hydroxyl substituents (Tsao, 2010).
Is phenolic water resistant?
What makes it “phenolic” is that both surface veneers are soaked in phenolic resin before attaching them to the plywood. This creates an extremely stable, smooth, durable, highly water resistant and attractive surface.
Does phenolic absorb water?
Phenolics are incredibly lightweight and have high water dissipation combined with low water absorption to make them a great option for watercraft and similar applications. They can withstand a wide range of temperatures and humidity and can be infused with flame retardant epoxy resins to make them flame resistant.
What is non phenolic?
Non-phenolic water contains almost exclusively NH3, H2S, and possibly a trace of CO2. It is generated by refinery hydro-treating (hydrodesulphurization or HDS) units. Phenolic (or more broadly, non-HDS) water typically contains heat stable salts (HSSs), HCN, phenols,and caustic.
Which is the correct definition of the word phenolic?
phe·no·lic | fi-ˈnō-lik , -ˈnä- . (Entry 1 of 2) 1a : of, relating to, or having the characteristics of a phenol. b : containing or derived from a phenol. 2 : of, relating to, or being a phenolic.
Which is more soluble in water phenol or water?
Phenol evaporates more slowly than water, and a moderate amount can form a solution with water. Phenol can catch fire. Phenol is used primarily in the production of phenolic resins and in the manufacture of nylon and other synthetic fibers.
What is the molecular weight of phenol PubChem?
Phenol PubChem CID 996 Synonyms phenol 108-95-2 carbolic acid Hydroxyben Molecular Weight 94.11 Date s Modify 2021-08-28 Create 2004-09-16
What does phenol look like in a liquid?
Phenol, liquid appears as a colorless liquid when pure, otherwise pink or red. Combustible. Flash point 175°F. Must be heated before ignition may occur easily. Vapors are heavier than air. Corrosive to skin but because of anesthetic qualities will numb rather than burn. Upon contact skin may turn white.
