Butadienes flash point

Benzene is a clear, colorless, flammable liquid with a pleasant characteristic odor, bp 80.1°C, flash point -11.1°C, and ignition temperature 538°C. Benzene has been found to be very toxic and is on the list of Known to Be Human Carcinogens published every two years by the Department of Health and Human Services under the National Toxicology Program (NTP). There are four top 50 chemicals on this worst carcinogen list benzene 1,3-butadiene ethylene oxide and vinyl chloride. There are also four chemicals in the top 50 on the Reasonably Anticipated to Be Human Carcinogens list acrylonitrile, ethylene dichloride, formaldehyde, and propylene oxide. 

Butadiene (1,3-butadiene, boiling point -4.4°C, density 0.6211, flash point -85°C) is made by steam cracking and by the dehydrogenation of butane or the butenes using an iron oxide (Fe203) catalyst. 

HEXACHLOROBUTADIENE or HEXACHLORO-l,3-BUTADIENE (87-68-3) C4C1 CliC=CClCCl=CCIj Combustible liquid (flash point 195°F/90°C autoignition temp 1125°F/607°C Fire Rating 1). Unless inhibited, may form unstable peroxides in storage. Reacts strongly with oxidizers, aliuninum powder may cause fire and explosion. Mixtures with bromine perchlorate forms heat-, friction-, and shock-sensitive explosive compound. Attacks aluminum, and some plastics and coatings decomposes rubber. Thermal decomposition releases toxic and irritating chloride fumes. On small fires, use dry... 

HYDROXYBENZENE (108-95-2) C HjOH Combustible solid, smelt (molten), or liquid [explosion limits in air (% by volume when heated) 3 to 10 flash point 174°F/79°C autoignition temp 1319°F/715°C Fire Rating 2]. Violent reaction with butadiene, strong oxidizers. Reacts, possibly violently, with strong acids ... 

BUTADIENE (106-99-0) Flammable gas (flash point - 105°F/-76°C). Self-reactive. In absence of an inhibitor, forms heat-, shock-, and impact-sensitive peroxides with air. Stabilize with terf-butyl catechol or other inhibitor and maintain levels at all times. Fires, explosions,... 

BUTADIENE DIOXIDE (111-42-2) Combustible liquid or crystalline solid (flash point 280°F/138°C). Strong reaction with strong oxidizers. Incompatible with nonoxidizing mineral acids, strong acids, organic acids, organic anhydrides, isocyanates, vinyl acetate, acrylates, substituted allyls, alkylene oxides, epichlorohydrin, aldehydes. Attacks aluminum, copper, zinc, and their alloys, and galvanized iron. 

BUTEN-3-YNE (689-97-4) Flammable gas (flash point <23°F/<—5°C). Unless inhibited, forms unstable peroxides with atmospheric oxygen or air. Heat, sunlight, oxygen, 1,3-butadiene, peroxides, oxidizers can cause explosive decomposition or polymerization. Forms sensitive and highly unstable metal acetylides with silver, cobalt, copper, magnesium, mercury, and their alloys.
