Ethyl glycollic ether

Glycollie Acid.—If a solution of 30 g. sodium glycollate in 38 cc. water is electrolyzed with a current strength of 1 amp., there are formed chiefly carbonic acid and formaldehyde,. besides a little carbon monoxide, formic acid, and oxygen (Miller and Hofer1). Walker2 obtained aldehyde in the electrolysis of the sodium salt of ethyl glycollic ether. 

Vinyl Ethers. The principal commercial vinyl ethers are methyl vinyl ether (methoxyethene, C H O) [107-25-5], ethyl vinyl ether (ethoxyethene, C HgO) [104-92-2], and butyl vinyl ether (1-ethenyloxybutane, C H 20) [111-34-2]. (See Table 8 for physical properties.) Others such as the isopropyl, isobutyl, hydroxybutyl, decyl, hexadecyl, and octadecyl ethers, as well as the divinyl ethers of butanediol and of triethylene glycol, have been offered as development chemicals (see Ethers). 

The manufacturing process for organo-soluble EHEC is similar to that for EC except that alkah cellulose reacts first with ethylene oxide to a low hydroxyethyl MS value of - 0.5 at a low temperature, - 50° C, followed by reaction of the ethyl chloride at a higher temperature. Additional by-products, which are removed during purification, include glycols and the reaction products of the glycols with ethyl chloride (glycol ethers).

Uses. Nearly half the ethyl alcohol produced in petrochemical plants (not the stuff fermented for human consumption) is used as a chemical intermediate in the manufacture of ethyl acrylate, ethyl amines, ethyl acetate (when you pop the cap on nail polish remover, you smell ethyl acetate), ethylene chloride, glycol ethers, acetaldehyde, and acetic acid. However, you will see in the chapters on acetaldehyde and acetic acid, there are now more competitive routes than those based on ethyl alcohol. 

SBA is primarily used as feedstock for methyl ethyl ketone. Other uses include hydraulic fluids, industrial cleaning compounds, paint remover, and an extracting agent for oils, perfumes, and dyes. TBA is used mostly as feedstock to make methyl methacrylate and glycol ethers (by reaction with ethylene or propylene oxides.) TBA is also a coproduct with PO, as covered in Chapter 11.

The selectivity of the Complex Formation is a very interesting subject, y - Cyclodextrin, (y - CD) has been found to form inclusion complexes with poly (methyl vinyl ether) (PMVE), poly(ethyl vinyl ether) (PEVE), and poly(n- propyl vinyl ether) (PnPVE) of various molecular weights to give stoichiometric compounds in crystalline states. However, a- cyclodextrin (a - CD) and (3 - Cyclodextrin ((3- CD) did not form complexes with poly (alkyl vinyl ether)s of any molecular weight, y -CD did not form complexes with the low molecular weight analogs, such as diethyl ether and trimethylene glycol dimethyl ether. 

Industrial uses of ethanol include solvents (especially for toiletries and cosmetics, coatings and inks, and detergents and household cleaners), and chemical intermediates (especially ethyl acrylate, vinegar, ethylamines, and glycol ethers). Most corn fermentation alcohol is used in fuel, industrial solvents and chemicals, and beverages. 

As many as 70 products were at one time produced commercially from ethanol. Some of these downstream products are butanol, 2-ethyl hexanol, crotonaldehyde, butyraldehyde, acetaldehyde, acetic acid, butadiene, sorbic acid, 2-ethylbutanol, ethyl ether, many esters, ethanol-glycol ethers, acetic anhydride, vinyl acetate, ethyl vinyl ether, even ethylene gas. Many of these products are now more economically made from other feedstocks such as ethylene for acetaldehyde and methanol-carbon monoxide for acetic acid. Time will tell when a revival of biologically-oriented processes will offer lower-cost routes to at least the simpler products. 

Since their commercial introduction in 1926, glycol ethers have become valuable as industrial solvents and chemical intermediates. Because glycol monoethers contain a -OCH2CH2OH group, they resemble a combination of ether and ethyl alcohol in solvent properties. The most common... 

Synthetic ethanol has the following uses as a chemical intermediate (for ethyl acetate, ethyl acrylate, glycol ethers, ethylamines, etc.), 30 percent in toiletries and cosmetics, 20 percent as a coatings solvent, 15 percent as a raw material for vinegar, 10 percent in household cleaners, 7 percent in detergents, 5 percent in pharmaceuticals, 5 percent in printing inks, 3 percent and in miscellaneous uses, 5 percent.
