Exempel på hur man kan använda PHTHALATE i en mening

• Potassium hydrogen phthalate (usually called KHP) for standardisation of aqueous base and perchloric acid in acetic acid solutions.
• PBX was first developed in 1952 at Los Alamos National Laboratory, as RDX embedded in polystyrene with diisooctyl phthalate (DEHP) plasticizer.
• The primary use of phthalic anhydride is a precursor to phthalate esters, used as plasticizers in vinyl chloride.
• Marketed under the brand name Dep, modern hair gel was given this name by its inventor, Luis Montoya, in recognition of the substance that gave it its unique, non-greasy consistency: diethyl phthalate, commonly abbreviated as DEP.
• 1 percent of di-(2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), or benzyl butyl phthalate (BBP).
• In April 2006, Cullen introduced a Private Member's Bill (Phthalate Control Act Bill C-307) to ban phthalates, a chemical in many plastics, from products intended for infants and toddlers.
• Different companies will use specific mixes of polymers and plasticizers (like dibutyl phthalate and dibutyl meleate) to make the spray paint flexible and durable.
• The production of the PVC used in the production of many artificial leathers requires a plasticizer called a phthalate to make it flexible and soft.
• In the phthalate 4,5-dioxygenase system, phthalate dioxygenase reductase (PDR) has the same function.
• These alternatives include other phthalates such as diisononyl phthalate (DINP), di-2-propyl heptyl phthalate (DPHP), diisodecyl phthalate (DIDP), and non-phthalates such as 1,2-cyclohexane dicarboxylic acid diisononyl ester (DINCH), dioctyl terephthalate (DOTP), and citrate esters.
• Benzyl butyl phthalate (BBP) is an organic compound historically used a plasticizer, but which has now been largely phased out due to health concerns.
• On November 20, 2017, at Agawam, Massachusetts, an operator error on TGP's Connecticut Expansion Project's pipeline test at the compressor station discharged 16,500 gallons of hazardous wastewater onto the soil of the compressor station yard; the wastewater contained heavy metals, lead, and carcinogens such as tetrachloroethylene and phthalate.
• 1 percent by weight of di-(2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), or benzyl butyl phthalate (BBP).
• In this system, the N-terminal P450 domain is fused to the reductase domain that shows sequence similarity to phthalate dioxygenase reductase and consists, in its turn, of FMN-binding domain and C-terminal plant-type ferredoxin domain.
• alt=Acid catalyzed reaction scheme of isobutanol and phthalic anhydride to form diisobutyl phthalate.
• Historically, cadmium iodide was used as a catalyst for the Henkel process, a high-temperature isomerisation of dipotassium phthalate to yield the terephthalate.
• S Environmental Protection Agency has classified Dimethyl phthalate as not classifiable for human carcinogenicity.
• Developed by American Cyanamid in the 1960s, the formulation containing CPPO, a fluorescer, and a glass capsule containing hydrogen peroxide and a base catalyst, all in dialkyl phthalate solvents, was marketed as Cyalume.
• Dibutyl phthalate (DBP) is an organic compound which is commonly used as a plasticizer because of its low toxicity and wide liquid range.
• Cellulose acetate phthalate is commonly plasticized with diethyl phthalate, a hydrophobic compound, or triethyl citrate, a hydrophilic compound; other compatible plasticizers are various phthalates, triacetin, dibutyl tartrate, glycerol, propylene glycol, tripropionin, triacetin citrate, acetylated monoglycerides, etc.
