"Phthalated" Natural Recordings by Native Speakers
The word "phthalated" refers to a group of chemicals that are phthalates, which are esters of phthalic acid. Phthalates are a class of synthetic chemical compounds that are commonly used as plasticizers, meaning they are added to plastics to make them softer and more flexible. They are found in a wide range of products, including plastics, adhesives, fragrances, and cosmetics.The term "phthalated" is often used in scientific and medical contexts to describe exposure or contamination by these chemicals. In recent years, there has been growing concern over the potential health risks associated with phthalate exposure, and as a result, some phthalates have been subject to regulation and restricted use.
The Phrygians were an ancient Anatolian people who lived in central and northwest Anatolia in what is now modern-day Turkey from the 8th to the 3rd century BC. They were named after their city, Phrygia, which was founded by King Mita of Phrygia, the ancestor of the Phrygians. They spoke a non-Indo-European language and established the Phrygian kingdom in Anatolia around 1180 BC.
The word "Phryma" can refer to several things:1. Phryma, a genus of flowering plants in the family Phrymaceae.2. Phryma, a genus of poetry in ancient Greece and Rome, referring to a type of lyric poetry.3. In biology, Phryma can also be used as a nomen nudum (a provisional name for an organism where the publication is incomplete or inadequate) for a genus of cycad-like plants.
The Phrymaceae are a family of plants in the order Lamiales, commonly known as Phrymaceae, which consists of four genera: Diplacus, Rostrinucula, Phryma, and Erythranthe. They are flowering plants that are native to various parts of the world, with the largest diversity of species in the Americas. These plants are annuals or perennials, often herbaceous, and have distinctive flowers that are usually two-lipped and characteristic of their family.
A Greek tragedy by Phrynichus, circa 476 BCE, that tells the story of the fall of Miletus to the Persians in 494 BCE.
The genus Phrynosoma refers to a group of small, spotted lizards commonly known as horned lizards. There are several species within this genus, primarily found in North America.
Phthalaldehyde is a chemical compound with the molecular formula C8H6O2. It is a colorless, odorless liquid with a melting point of 261-262°C.
Phthalates are a group of synthetic chemicals used to soften plastics and make them more flexible. They are often found in a wide range of everyday products, including cosmetics, soaps, shampoos, plastics, adhesives, and packaging materials. Phthalates are known to be endocrine disruptors, which means they can interfere with the body's hormonal system. Long-term exposure to certain phthalates has been linked to reproductive problems, birth defects, and other health issues in humans and animals.
Phthalein is a group of chemical compounds that are derived from naphthalene. The oldest known derivative, 1-hydroxynaphthalene (1-hydroxyphthalan), was discovered in 1804.However, the term "phthalein" is more commonly used to refer to a specific class of compounds called the phthalate dyes, which are azo compounds (dyes containing a nitro group and a benzene ring linked by a nitrogen atom) that are used as indicators to the presence of alkaline substances and acids. The most well-known example is phenolphthalein, a pH indicator used in chemistry to distinguish between acidic and alkaline substances.
Phthalide is a type of naturally occurring compound that is a sub-class of lactones. Lactones are a type of organic chemical compound that contains a ring structure with a carbonyl group (CO) in an oxygen heterocycle. Phthalides are characterized by a six-membered ring with an oxygen and a side chain attached to it.
Phthalimide (C8H5NO) is a crystalline compound obtained from phthalic anhydride by treatment with ammonia, NH3, or by other methods. It is used as an intermediate for the manufacture of dyes, resins, and pharmaceuticals such as sulfonamides. It is a colorless, crystalline solid that melts at 25-26°C and has a molecular weight of 145.13 g/mol.
Phthalo is a synthetic pigment, a group of bright blue and green pigments that are used in various art applications, including painting and printing. It is known for its vibrant color strength and lightfastness, which means it maintains its color over time when exposed to light. Phthalo green is also highly resistant to fading and bleeding, making it a popular choice among artists and designers. There are two main types of phthalo pigments: phthalo green (Blue Phthalo or PG7) and phthalo blue (Red Phthalo or PB15:3).In chemistry, phthalo refers to a class of organic compounds containing the 3H-phthalazin-1-one or 3H-isoindole-1,3-dione ring systems, which can be derived from phthalic anhydride and various amines. These compounds are used in various applications, including pharmaceuticals, dyes, and pigments.
Phthalocyanines are a family of synthetic pigments that belong to the group of heterocyclic aromatic compounds. They consist of a planar, ring-like structure (macrocyclic) whose four corner nitrogen atoms are bonded to a four-atom ligand (usually carbon), and have a total of 26 atoms.Phthalocyanines are all blue pigments or green, except those bearing a pendant group with a hydrogen atom(s) bonded to the nitrogen atom, which may also be green or red.Examples of phthalocyanines include:<em> Aluminum phthalocyanine chloride, a green pigment used in paints, inks and plastics.</em> Phthalocyanine green B, a blue pigment used in the printing industry.<em> Phthalocyanine blue G (PB16B), a deep blue pigment used in paints and printing.</em> Phthalocyanine green B (PG7) a pigment used in fillers.<em> Vanadyl phthalocyanine (deuteroporphycene), a bright blue porphyrin</em> Organic photovoltaic solar cells using a combination of a copper phthalocyanine with a subphthalocyanine have been shown to have the best power conversion efficiency.
