52 [vol. 6, THE DISTRIBUTION OF PHOSPHORUS IN COW'S MILK AND THE SCHEME FOR THE SEPARATION OF PHOSPHATIDES By Rinjiro SASAKI (From the Institute of Agricultural Chemistry, College of Agriculture, Tokyo Imperial University) (Received 9th September 1930) A. The Distribution of Phosphorus in Cow's milk In order to extract the phosphatides, it is necessary first to determine the distribution of phosphorus in cow's milk. Liquid milk can not be extracted with ether or with other organic solvents owing to its large content of water. The substance applied in this experiment is the milk powder, dried by the Buflovak drum drier below 70•Ž. Its content of moisture is 4.498%, deter mined by the method of drying in the air bath of 105•Ž. The content of total phosphorus was determined(5) in the ash of sample which was burned with a little of fusing mixture. In 100g. of milk powder In 100g. of dry matter Total phosphorus 0.745g. 0.781g. The amounts of phosphorus, which are soluble in the various organic sol vents, were determined by extracting with three solvents in the following orders. (A) Ether-Acetone-Alcohol (B) Acetone-Ether-Alcohol (C) Alcohol-Ether-Acetone Experiment (A) 1) At first a pair of each 10g. of sample was extracted with ether by the Soxhlet's apparatus for a week. After the extraction had been comp leted, the extract was freed from ether and weighed. In 100g.of milkpowder In 100g.of dry matter Total ether matters soluble 3.609g. 3.779g. 2) The above extract was dissolved in a very little of ether. -

Transition Metal Phosphides for the Catalytic Hydrodeoxygenation of Waste Oils Into Green Diesel
catalysts Review Transition Metal Phosphides for the Catalytic Hydrodeoxygenation of Waste Oils into Green Diesel M. Consuelo Alvarez-Galvan * , Jose M. Campos-Martin * and Jose L. G. Fierro * Energy and Sustainable Chemistry Group (EQS), Instituto de Catálisis y Petroleoquímica, CSIC, c/Marie Curie, 2 Cantoblanco, 28049 Madrid, Spain * Correspondence: [email protected] (M.C.A.-G.); [email protected] (J.M.C.-M.); jlgfi[email protected] (J.L.G.F.) Received: 28 February 2019; Accepted: 15 March 2019; Published: 22 March 2019 Abstract: Recently, catalysts based on transition metal phosphides (TMPs) have attracted increasing interest for their use in hydrodeoxygenation (HDO) processes destined to synthesize biofuels (green or renewable diesel) from waste vegetable oils and fats (known as hydrotreated vegetable oils (HVO)), or from bio-oils. This fossil-free diesel product is produced completely from renewable raw materials with exceptional quality. These efficient HDO catalysts present electronic properties similar to noble metals, are cost-efficient, and are more stable and resistant to the presence of water than other classical catalytic formulations used for hydrotreatment reactions based on transition metal sulfides, but they do not require the continuous supply of a sulfide source. TMPs develop a bifunctional character (metallic and acidic) and present tunable catalytic properties related to the metal type, phosphorous-metal ratio, support nature, texture properties, and so on. Here, the recent progress in TMP-based catalysts for HDO of waste oils is reviewed. First, the use of TMPs in catalysis is addressed; then, the general aspects of green diesel (from bio-oils or from waste vegetable oils and fats) production by HDO of nonedible oil compounds are presented; and, finally, we attempt to describe the main advances in the development of catalysts based on TMPs for HDO, with an emphasis on the influence of the nature of active phases and effects of phosphorous, promoters, and preparation methods on reactivity. -
Cool Reaction the Endothermic Reaction Between SCIENTIFIC Barium Hydroxide and Ammonium Thiocyanate
Cool Reaction The Endothermic Reaction Between SCIENTIFIC Barium Hydroxide and Ammonium Thiocyanate Introduction Many reactions produce heat, in fact when people think of chemical reactions, heat production is often expected. However, endothermic reactions, reactions which consume heat, can be just as exciting. One of the most striking examples of this is when the solids barium hydroxide and ammonium thiocyanate are mixed together in a beaker. Materials Ammonium thiocyanate, NH4SCN, 10 g Stirring rod Barium hydroxide octahydrate, Ba(OH)28H2O, 20 g Thermometer graduated to at least –30 °C Erlenmeyer flask, small, with stopper, or a 50-mL beaker Safety Precautions Barium salts are toxic by ingestion. Ammonium thiocyanate is also toxic by ingestion. Use caution when handling the beaker or flask. Use tongs if available. The temperatures involved are cold enough to freeze skin. Ammonia vapor is very irritating to eyes and the respiratory tract. Do not allow students to inhale this gas. Wear chemical splash goggles, chemical-resistant gloves, and a chemical-resistant apron. Please review current Material Safety Data Sheets for additional safety, handling, and disposal information. Procedure 1. Transfer 20 g of barium hydroxide and 10 g of ammonium thiocyanate to a flask and mix with a glass or plastic stirring rod. 2. In less than two minutes the solids become liquid. A thermometer placed in the mixture shows the temperature falling far below freezing. An ammonia odor is evident to all who are near the flask. 3. Place the flask in a small puddle of water and your students will clearly see just how cool this reaction is; the water will freeze the flask to the counter top. -
