GPS Safety Summary. 1-Butene. Technical information. Substance name. 1-Butene CAS-No General Statement

Transcription

1 Technical information GPS Safety Summary Substance name CAS-No General Statement is a colorless, combustible gas with a characteristic odor. It is easily condensable under pressure. is soluble in hydrocarbons, alcohols and ethers, but virtually insoluble in water (0,5 g/l at 20 C). is classified as an extremely flammable gas. It is stored and transported as a liquified gas. In its chemical behaviour it shows the typical reactions of olefins like hydrogenation, electrophilic addition, oxidation and polymerization. Therefore the substance is used as an intermediate or monomer mainly. Chemical identity Name Brand names Butene-1 Chemical name (IUPAC) but-1-ene CAS number Molecular formula Structure Chemical characterization C4H8 H2C=CHCH2CH3 Lower olefine Evonik Indu I ndustries AG GPS Safety Summary November 2011 Version 1 page 1/6

2 Uses and application is used mainly as a co-monomer for polyethylene (LLDPE, HDPE) or co-monomer for ethylene/propylene copolymers where it improves for example the tear strength of the polymer. Further it is used as intermediate for the production of various products, for example antioxidants, plasticizers, herbicides, corrosion inhibitors or additives to lubricating and hydraulic oils. It may be used to a minor extent as fuel. Physical/chemical properies is an extremely flammable gas. The boiling point indicates that the substance has a high volatility. Water solubility is low. In case of a release the majority will distribute in air. Property Value Physical state Liquified gas Color Colorless Odor Olefin-like Density 0.59 g/cm3 (liquid) Melting / boiling point -185 C / -6.1 C Flammability extremely flammable gas Explosive Properties Not to be expected in view of the structure, however may form explosive mixtures with air: explosion limits 1.6% (V) -10 % (V) Self-ignition temperature 384 C Vapor pressure 2545 hpa (20 C) Molecular weight 56,1 g/mol Water solubility 0.5 g/l Flash point < -40 C Octanol-water partition 2.42 coefficient AG GPS Safety Summary November 2011 Version 1 page 2/6

3 Health effects Effect Assessment Result Acute toxicity (oral, dermal and inhalation) Eye / Skin irritation Sensitization Toxicity after repeated exposure Genotoxicity/mutagenicity Carcinogenicity Toxicity for reproduction Low acute toxicity, but due to oxygen loss narcotic effects at very high concentrations possible No data available because product is a gas. Contact with liquid causes frost-bite. Not considered to be sensitizing Low level long-term toxicity Not mutagenic in a battery of in-vitro test systems. In vitro and animal experiments revealed no evidence of potential for hereditary genetic changes. According to the results for repeated dose toxicity and mutagenicity tests, carcinogenic effects are not to be expected No adverse effects on fertility and not selectively toxic to the fetus Environmental effects Effect Assessment Aquatic toxicity Result The substance is a highly volatile gas. Therefore relevant concentrations in aquatic environment which may cause harmful effects are not to be expected Fate and Behavior Biodegradation Bioaccumulation potential PBT / vpvb conclusion Result Substance is a volatile gas. Therefore tests are technically not possible. Structure activity calculations demonstrate readily biodegradability. Because of the low partition coefficient n-octanol-water not to be expected. Neither considered to be PBT nor vpvb is not expected to persist in the environment because it is AG GPS Safety Summary November 2011 Version 1 page 3/6

4 predicted to degrade rapidly in water and air, has a low potential for adsorption to organic matter and has a low potential for bioaccumulation. Exposure Human health is a highly flammable gas and must therefore be handled in closed systems with low level of exposure. Production and use take place in chemical industry with an according safety standard. Environment Because the substance is produced and used as a monomer or intermediate in closed systems no relevant exposure in environment is to be expected. In the air substance is photochemically degradable. No relevant concentrations in aquatic environment to be expected because substance is a gas. Risk management recommendations Industry use, production and formulation The usual protection measures when highly flammable gases are handled have to be observed. Wear personal protective equipment Avoid contact with skin and eyes. Do not inhale vapors / aerosols. Provide good ventilation or extraction. Ensure good room ventilation at floor level too. Vapors are heavier than air and may spread along floors. Take precautionary measures against static charges, keep away from sources of ignition. Explosion protection equipment required. Keep away from flames and hot surfaces. Avoid heat effect and sources of ignition. No smoking. Do not empty into drains. If positive displacement pumps are used, these must be fitted with non-integral pressure relief valve. Priority should be given to closed-system units. Observe special instructions applicable to compressed gases. Keep containers tightly closed in a cool, well-ventilated place with exclusion of air/oxygen Consumer use Only in combination with other more dangerous substances in fuel, but to a minor extent only.
