BUTYNOL SYSTEM SPECIFICATION A synthetic rubber with properties which resist ageing from heat, sunlight and ozone. It has excellent gas impermeability and toughness and remains flexible at low temperatures. Butynol is manufactured by combining the petroleum gases isobutylene and isoprene at the extremely low temperature of -100°C. (Rubber Technology-Morton) Butynol is marketed by Ardex as a warranted roofing and tanking product and fixed by their trained and experienced approved Applicators. BUTYNOL MATERIAL SPECIFICATIONS Our requirements for long term warranty necessitate that Butynol meets these typical technical requirements: Specific Gravity to ASTM D297 1.20±0.05 Hardness IRHD to ASTM D1415 65±5 Tensile Strength to ASTM D412 8.3 MPa min Modulus at 300% elongation to ASTM D412 4.15 MPa min Elongation at break to ASTM D412 300% min Heat Ageing (7 days at 115° C) Tensile Retention to ASTM D412 70% min Elongation Retention to ASTM D412 70% min Tear Strength to ASTM D624 26kN/m Ozone Resistance to ASTM D1149 No visible cracks
(7 days at 40°C in 50pphm ozone) Water Absorption to ASTM D471

What is the viscosity of butanol in millipoise?
The viscosity of n-butanol is 2,593.10-3 Pa.s or 25,93 millipoise.
Why is acid catalyzed dehydration of tertiary butanol faster than that of n-butanol?
sulphuric acid
Is butanol a base?
In spite of the same OH group as in bases, butanol is not a hydroxide (base, alkaline) it is an alcohol (alkanol) in the organic group of compounds: they do not ionise or hydrolyse in water, no OH- ions are split off.There are 3 formula isomers of butanol: CH2OH-CH2-CH2-CH3 (1-butanol) and CH3-CH(OH)-CH2-CH3 (2R-butanol) and CH3-C(OH)H-CH2-CH3 (2S-butanol), the '2R' and '2S' butanol formula's are mirror isomers.
What is C4H9OH?
butylalcohol (butanol)
Is butanol a reactant?
yes it is
Is water soluble in 1-butanol?
The solubility of 1-butanol in water is 90g Butanol / L Water. Butanol, being an alcohol, is slightly polar.
2-butanol immersible in water why?
2-butanol is miscible with water.
What is the condensed structure of 1-butanol?
ch3ch2ch2choh This is i-butanol CH3CH2CH2CHOH.Thanks mosynoe

7
What is the chemical formula for 2-methyl-2-butanol?
The chemical formula of 2-methyl-2-butanol is C15H12O.
Butanol weight per gallon?
Butanol has a density of 810 kilograms per cubic meter. 1 gallon is equal to .00378541 cubic meters. Then, 1 gallon of butanol has a mass of 3.07 kilograms.
