In the 1940s, Sherwin-Williams introduced Kem-Tone, a water-based fast-drying interior paint. [4] In 1996, the American Chemical Society named the product a National Historic Chemical Landmark. [14] [15] In 2016, the first paint registered as microbicidal with the United States Environmental Protection Agency was brought to market by Sherwin ...
2,2-Dichloro-1,1,1-trifluoroethane or HCFC-123 is considered as an alternative to CFC-11 in low pressure refrigeration and HVAC systems, and should not be used in foam blowing processes or solvent applications.
A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%). B Calculated values *Derived data by calculation.
H. C. Evans & Company of Chicago was once a leading manufacturer of casino equipment and supplies - both honest and crooked - in the United States. It was established in 1892 and collapsed in 1955. It was established in 1892 and collapsed in 1955.
1958 sales team promotional newsletter excerpts. Niles Foster, a former bakery and bottling plant owner, created Hi-C in 1946. It took Foster over a year to develop the ideal formula for Hi-C orange drink; the formula contains orange juice concentrate, peel oil and orange essences, sugar, water, citric acid and ascorbic acid (vitamin C).
Tritiated water is a radioactive form of water in which the usual protium atoms are replaced with tritium atoms. In its pure form it may be called tritium oxide (T 2 O or 3 H 2 O) or super-heavy water. Pure T 2 O is a colorless liquid, [1] and it is corrosive due to self-radiolysis. Diluted, tritiated water is mainly H 2 O plus some HTO (3 HOH).
Acryloyl chloride can be efficiently prepared by treating acrylic acid with benzoyl chloride: [2]. CH 2 =CHCO 2 H + C 6 H 5 COCl → CH 2 =CHCOCl + C 6 H 5 CO 2 H. Conventional phosphorus-based chlorinating agents, e.g. phosphorus trichloride, are ineffective.
Trifluoroacetyl chloride has a vapor density that is 4.6 times that of air, or about 1.384 grams per milliliter at 20 °C (68 °F) as a liquid under pressure. [1] [2] The compound has a melting point of −146 °C (−231 °F) and a boiling point of −27 °C (−17 °F). [2]
