123-20-6 Usage
Uses
Vinyl Butyrate is a general chemical reagent used in the synthesis of isoxazolidines.
General Description
A colorless liquid. Less dense than water. Flash point 68°F. Vapors heavier than air. Used to make plastics and paints.
Air & Water Reactions
Highly flammable. Slightly soluble in water.
Reactivity Profile
VINYL BUTYRATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Health Hazard
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. May polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Safety Profile
Mddly toxic by
inhalation and ingestion. A skin and eye
irritant. A 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, fog, mist, CO2. When heated
to decomposition it emits acrid smoke and
irritating fumes. See also ESTERS.
Check Digit Verification of cas no
The CAS Registry Mumber 123-20-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123-20:
(5*1)+(4*2)+(3*3)+(2*2)+(1*0)=26
26 % 10 = 6
So 123-20-6 is a valid CAS Registry Number.

Synthesis of higher vinyl esters from ethylene and higher carboxylic acids
-
, (2008/06/13)
A homogeneous liquid phase process for producing a vinyl carboxylate in which the carboxylate group contains at least four carbon atoms, which process comprises (1) forming a homogeneous liquid reaction mixture containing ethylene, oxygen carboxylic acid having at least three carbon atoms, a palladium (II) catalyst and a copper (II) oxidant and (2) maintaining the reaction mixture under conditions at which the ethylene and the carboxylic acid react to form the vinyl carboxylate in the homogeneous liquid reaction mixture, with the proviso that at least one of the following conditions exists during said process: (i) the copper (II) oxidant is a copper (II) carboxylate in which carboxylate group has a molecular weight that is higher than the molecular weight of the carboxylate group in the carboxylic acid; (ii) the palladium (II) catalyst is formed in situ in the reaction mixture by the oxidation of a palladium (0) colloid; and/or (iii) the reaction mixture also contains a polyglyme compound as a promoter.
A novel synthesis of vinyl esters from vinylversatate-10
Mondal,Van Der Meer,German,Heikens
, p. 4205 - 4207 (2007/10/05)
Vinylversatate-10 (VV10)1 1 VV 10 Vinyl Monomer, Development Product, Shell Chemical Company has successfully been used to synthesise a large number of lower vinyl esters by transvinylation in presence of mercuric acetate and sulfuric acid. The synthesis of vinylhalo esters proceeds with more difficulty. It has been observed that neither Hg(OAc)2 nor H2SO4 alone is capable of initiating the transvinylation. Furthermore, it has been found that a molar ratio 2:1 of VV10 to carboxylic acid is sufficient to drive the reaction to the right by continuous distillation of the vinyl ester formed, and as a result a high yield of vinyl ester is obtained. A mechanism for this reaction and for the formation of side products has been proposed.
