No #knockknockjokes possible with this #molecule 2,2,4-#Trimethylpentane, also known as #isooctane or iso-octane, is an organic compound with the formula (CH3)3CCH2CH(CH3)2. It is one of several isomers of #octane (C8H18). This particular isomer is the standard 100 point on the octane rating scale (the zero point is n-heptane). It is an important component of #gasoline, frequently used in relatively large proportions to increase the #knockresistance of the #fuel. #staynerdy #chemistry #moleculeoftheday #science #orgo #molecules #moleculelove #chemistrylove #beautifulchemistry

Hydrogen fluoride (HF) is a compound essential to society, yet so dangerous it is feared even by many trained chemists. The anhydrous form is a colorless, easily liquefied gas (bp 19.5 °C). When the gas dissolves in water, hydrofluoric acid is formed (~48% solution is a common reagent). HF corrodes through almost every material, including glass and bones, due to the strong bonds fluorine forms with other atoms. Skin contact with HF causes severe burns that may not be initially painful due to nerve interference. If treatment is delayed, fluoride absorbed into the blood sequesters calcium and magnesium ions, which leads to excruciating pain and cardiac arrest. HF vapors cause blindness and pulmonary edema. In spite of all this, HF is safely handled in many industrial processes. Sulfuric acid is used to extract HF from the abundant mineral fluorite (CaF2); in this manner, HF is the precursor to all fluorine compounds. Examples include PTFE (Teflon, a robust polymer with hundreds of uses), cryolite (Na3AlF6, central to aluminum production), and fluoride salts (for cavity prevention). In the petrochemical industry, HF is a catalyst for upgrading crude oil fractions into alkylate (gasoline stock) and linear alkylbenzene (basis of all modern detergent). Furthermore, hydrofluoric acid is used to etch silicon wafers for consumer electronics. #forbiddensnacks #chemistry #organicchemistry #inorganicchemistry #chemistrylab #chemistry_lab #chemistrylife #chemistrylifestyle #chemistryfun #chemistryisfun #chemistrylove #chemistrylovers #chemistrydaily #chemistrynotes #chemistryeducation #quimica #chemie #science #chemical #chemicals #molecule #molecules #moleculeoftheday #fluorine #hydrofluoricacid #fluoride #calcium #aluminum #teflon #gasoline

This molecule is spelled FFFFFFFFFFFFFFFuuuu*k Perfluorooctanoic acid (#PFOA) (conjugate base #perfluorooctanoate) is a perfluorinated carboxylic acid produced and used worldwide as an industrial #surfactant in #chemical processes and as a material feedstock, and is known as an emerging health concern and subject of regulatory action and voluntary industrial phase-outs. PFOA is used for several industrial applications, including carpeting, upholstery, apparel, floor wax, textiles, sealants, and cookware. PFOA serves as a surfactant in the emulsion #polymerization of #fluoropolymers and as a building block for the synthesis of perfluoroalkyl-substituted compounds, polymers, and polymeric materials. PFOA persists indefinitely in the environment. It is toxic. As it is a suspected #carcinogen, various studies have been undertaken, but no link between PFOA and cancer emerged, although it remains suspect and under investigation. Another study of workers living near a DuPont Teflon plant found an association between PFOA exposure and two kinds of cancer as well as four other diseases. PFOA has been detected in the blood of more than 98% of the general US population in the low and sub-parts per billion (ppb) range, and levels are higher in chemical plant employees and surrounding subpopulations. How general populations are exposed to PFOA is not completely understood. PFOA has been detected in industrial waste, stain-resistant carpets, carpet-cleaning liquids, house dust, microwave popcorn bags, water, food, some cookware and #Teflon (#PTFE) products.
