Definition
ChEBI: An alkene that is but-1-ene carrying a methyl substituent at position 3.
General Description
A colorless volatile liquid with a disagreeable odor. Insoluble in water and less dense than water. Vapors heavier than air. Flash point below 0°F. Used to make other chemicals.
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
3-Methyl-1-butene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.
Hazard
Highly flammable, dangerous fire and
explosion risk, explosive limits 1.6–9.1%.
Health Hazard
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Safety Profile
Very dangerous fire
hazard when exposed to heat, flame, or
oxidizers. Explosive in the form of vapor
when exposed to heat or flame. To fight
fire, use alcohol foam, mist, spray, dry
chemical, CO2. When heated to
decomposition it emits acrid smoke and
irritating fumes. See also 2-METHYL-1
BUTENE.
Source
Schauer et al. (1999) reported 3-methyl-1-butene in a diesel-powered medium-duty truck
exhaust at an emission rate of 160 μg/km.
Schauer et al. (2001) measured organic compound emission rates for volatile organic
compounds, gas-phase semi-volatile organic compounds, and particle-phase organic compounds
from the residential (fireplace) combustion of pine, oak, and eucalyptus. The gas-phase emission
rate of 3-methyl-1-butene was 6.9 mg/kg of pine burned. Emission rates of 3-methyl-1-butene
were not measured during the combustion of oak and eucalyptus.
California Phase II reformulated gasoline contained 3-methyl-1-butene at a concentration of 380
mg/kg. Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without
catalytic converters were 0.35 and 22.5 mg/km, respectively (Schauer et al., 2002).
Environmental fate
Photolytic. The following rate constants were reported for the reaction of 3-methyl-1-butene and
OH radicals in the atmosphere: 3.0 x 10-11 cm3/molecule?sec (Atkinson et al., 1979); 6.07 to 9.01 x
10-11 cm3/molecule?sec (Atkinson, 1985); 3.18 x 10-11 cm3/molecule?sec (Atkinson, 1990).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water.
Check Digit Verification of cas no
The CAS Registry Mumber 563-45-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 563-45:
(5*5)+(4*6)+(3*3)+(2*4)+(1*5)=71
71 % 10 = 1
So 563-45-1 is a valid CAS Registry Number.

Paragraph 0056; 0122; 0123, (2021/03/13)
A catalyst for dehydrogenation of hydrocarbons includes a support including zirconium oxide and Linde type L zeolite (L-zeolite). A concentration of the zirconium oxide in the catalyst is in a range of from 0.1 weight percent (wt. %) to 20 wt. %. The catalyst includes from 5 wt. % to 15 wt. % of an alkali metal or alkaline earth metal. The catalyst includes from 0.1 wt. % to 10 wt. % of tin. The catalyst includes from 0.1 wt. % to 8 wt. % of a platinum group metal. The alkali metal or alkaline earth metal, tin, and platinum group metal are disposed on the support.
Competitive adsorptions between thiophenic compounds over a CoMoS/Al2O3 catalyst under deep HDS of FCC gasoline
dos Santos, Alan Silva,Girard, Etienne,Leflaive, Philibert,Brunet, Sylvette
, p. 292 - 298 (2018/12/11)
The transformation of various model sulfur compounds (2-methylthiophene: 2MT, 3-methylthiophene: 3MT and benzothiophene: BT) representative of sulfur compounds in FCC gasoline was investigated over a CoMoS/Al2O3 catalyst. More specifically, a quantitative reactivity scale was established with BT being more reactive than 3MT and 2MT. In mixture, their reactivity was reduced due to the presence of the other sulfur compound, the scale of reactivity being preserved. BT strongly inhibits the transformation of 2MT. With a single kinetic model based on a Langmuir Hinshelwood formalism, kinetic and adsorption parameters were calculated and the results explained by mutual competitive adsorption between 2MT and BT with a higher adsorption constant for BT compared to that of 2MT.
