109-53-5 Usage
Chemical Properties
Colorless liquid. Very
slightly soluble in water; soluble in alcohol and
ether; easily polymerized.
Uses
Different sources of media describe the Uses of 109-53-5 differently. You can refer to the following data:
1. Isobutyl vinyl ether is use in preparation method and formula of bulk polymerized Chloroether resin.
2. Polymer and copolymers used in surgical adhesives,
coatings, and lacquers; modifier for alkyd and
polystyrene resins; plasticizer for nitrocellulose and
other plastics; chemical intermediate.
General Description
A clear colorless liquid. Flash point 15°F. May polymerize if contaminated or subjected to heat. If polymerization take place inside a container, the container may violently rupture. Vapors are heavier than air.
Air & Water Reactions
Highly flammable. Less dense than water and very slightly soluble in water. Tends to form explosive peroxides when exposed to air. When ethers containing peroxides are heated (distilled) they can detonate [Lewis, 3rd ed., 1993, p. 728].
Reactivity Profile
Isobutyl vinyl ether is a colorless, moderately toxic liquid, highly flammable. A very dangerous fire hazard when exposed to heat, flame or strong oxidizing agents. Highly explosive in the form of vapor when exposed to open flame or sparks.
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 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.
Flammability and Explosibility
Flammable
Purification Methods
Wash the ether three times with equal volumes of aqueous 1% NaOH, dry with CaH2, reflux it with sodium for several hours, then fractionally distil it from sodium. [Beilstein 1 IV 2054.]
Check Digit Verification of cas no
The CAS Registry Mumber 109-53-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109-53:
(5*1)+(4*0)+(3*9)+(2*5)+(1*3)=45
45 % 10 = 5
So 109-53-5 is a valid CAS Registry Number.

Calcium Carbide Looping System for Acetaldehyde Manufacturing from Virtually any Carbon Source
Rodygin, Konstantin S.,Lotsman, Kristina A.,Ananikov, Valentine P.
, p. 3679 - 3685 (2020/06/17)
A vinylation/devinylation looping system for acetaldehyde manufacturing was evaluated. Vinylation of iso-butanol with calcium carbide under solvent-free conditions was combined with hydrolysis of the resulting iso-butyl vinyl ether under slightly acidic conditions. Acetaldehyde produced by hydrolysis was collected from the reaction mixture by simple distillation, and the remaining alcohol was redirected to the vinylation step. All the inorganic co-reagents can be looped as well, and the full sequence is totally sustainable. A complete acetaldehyde manufacturing cycle was proposed on the basis of the developed procedure. The cycle was fed with calcium carbide and produced the aldehyde as a single product in a total preparative yield of 97 %. No solvents, hydrocarbons, or metal catalysts were needed to maintain the cycle. As calcium carbide in principle can be synthesized from virtually any source of carbon, the developed technology represents an excellent example of biomass and waste conversion into a valuable industrial product.

Page/Page column 9-10, (2008/06/13)
A process for the production of alkenyl ethers represented by the general formula (III) [wherein R1, R2 and R3 are each independently hydrogen, substituted or unsubstituted alkyl, or the like; n is an integer of 1 or above; and X is a group derived from substituted or unsubstituted alkane by removing n hydrogen atoms (which alkane includes those substituted with one or two aryl groups and the carbon atoms of which alkane may be partially replaced by oxygen or SO2), or the like], characterized by comprising the step of reacting a compound represented by the general formula (I) (wherein R1, R2 and R3 are each as defined above) with a compound represented by the general formula (II) (wherein n and X are each as defined above) and hydrogen halide to obtain an α-halo ether.
