628-32-0 Usage
Uses
Ethyl Propyl Ether (cas# 628-32-0) is used in the composition of methanol fuel for vehicles which solves the problems of vehicle methanol fuel meeting water and low temperature stratification, rubber swelling, metal corrosion, hot air resistance, and cold start.
General Description
A colorless liquid with an ether-like odor. Less dense than water. Flash point below 0°F. Vapors heavier than air. Used to make other chemicals.
Air & Water Reactions
Highly flammable. Soluble in water. Ethers tend to form unstable peroxides when exposed to oxygen. Ethyl, isobutyl, ethyl tert-butyl, and ethyl tert-pentyl ether are particularly hazardous in this respect. Ether peroxides can sometimes be observed as clear crystals deposited on containers or along the surface of the liquid.
Reactivity Profile
Ethers, such as ETHYL N-PROPYL ETHER, can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.
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. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Safety Profile
A slight inhalation
hazard. Very dangerous fire and explosion
hazard when exposed to heat or open flame.
To fight fire, use alcohol foam. When
heated to decomposition it emits acrid
smoke and fumes. See also ETHERS.
Check Digit Verification of cas no
The CAS Registry Mumber 628-32-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 628-32:
(5*6)+(4*2)+(3*8)+(2*3)+(1*2)=70
70 % 10 = 0
So 628-32-0 is a valid CAS Registry Number.

Page/Page column 19-21, (2019/05/10)
The present invention relates to a selective process for preparing acetals or ethers. In particular, the process involves a selective catalytic hydrogenolysis of a trihydrocarbyl orthoesterso as to control the extent of dealcoholation to afford either the corresponding acetal or ether product. Ether products preparable by means of the present invention include ethers which are suitable for use as base stocks in lubricating compositions.

Complexes of cobalt and nickel with tridentate ligand PNHPR are effective for hydrogenation of unsaturated compounds. Cobalt complex [(PNHPCy)Co(CH2SiMe3)]BArF4 (PNHPCy=bis[2-(dicyclohexylphosphino)ethyl]amine, BArF4=B(3,5-(CF3)2C6H3)4)) was prepared and used with hydrogen for hydrogenation of alkenes, aldehydes, ketones, and imines under mild conditions (25-60° C., 1-4 atm H2). Nickel complex [(PNHPCy)Ni(H)]BPh4 was used for hydrogenation of styrene and 1-octene under mild conditions. (PNPCy)Ni(H) was used for hydrogenating alkenes.
On the miscibility of ethers and perfluorocarbons. An experimental and theoretical study
Babiak, Peter,Němcová, Adriana,Rulí?ek, Lubomír,Beier, Petr
, p. 397 - 401 (2008/12/21)
Despite their significant polar character, some organic ethers such as diethyl ether were found to be miscible with perfluorocarbon solvents. Solubilities of various ethers in perfluorocarbons and miscibility temperatures were determined. These properties were found to be greatly dependent on the polarity but also size and shape of the ether molecule. Theoretical calculations of the miscibility temperatures of organic solvents and perfluorocarbons using COSMO-RS method were correlated with experimental data. Considering the difficulties in the accurate description of the macroscopic properties, such as miscibility temperatures, from the first principles, the agreement between experimental and theoretical data is reasonable.
