Free Acetic Acid Transfer 10.0 g of sample into a 250-mL glass-stoppered Erlenmeyer flask, dissolve in 75 mL of ethylene dichloride, add 60 mL of specially denatured ethanol formula 2B, and mix. Add phenolphthalein TS, and titrate with 0.02 N methanolic potassium hydroxide to a faint pink endpoint. Perform a blank determination (see General Provisions), and make any necessary correction. Each milliliter of 0.02 N methanolic potassium hydroxide is equivalent to 1.201 mg of C2H402.

Methods involving the optical rotation of camphor are of little value as synthetic camphor, which is practically devoid of rotatory power, is now used and the rotations of solutions of natural camphor differ according to the solvent. In ethanolic solution the highest specific rotatory power is obtained by measurement of a weak solution of camphor in strong ethanol formulae have been derived to calculate the percentage from rotation in given solvents (Partheil and Van Haaren Schoorl ). 

Note also that if another ester, of general formula R-COOCjHj, were used in place of benzaldehyde in the above reaction, a similar complex would be formed, and on acidification would give an unstable p-hydroxy-P-ethoxy ester, which would very readily lose ethanol with the formation of a 3-keto-ester. 

On being heated with a solution of sodium ethoxide in ethanol compound A (CyHisBr) yielded a mixture of two alkenes B and C each having the molecular formula C7H14 Catalytic hydrogenation of the major isomer B or the minor isomer C gave only 3 ethylpentane Suggest structures for compounds A B and C consistent with these observations...

Atoms combine in definite proportions to give molecules. For example, natural gas is mostly composed of methane, a substance in which four hydrogen atoms (H) are combined with one carbon (C) the molecular formula is written as CH4. Similarly, water, ammonia, ethanol, and glucose have... 

Solvents. The most widely used solvent is deionized water primarily because it is cheap and readily available. Other solvents include ethanol, propjdene glycol or butylene glycol, sorbitol, and ethoxylated nonionic surfactants. There is a trend in styling products toward alcohol-free formulas. This may have consumer appeal, but limits the formulator to using water-soluble polymers, and requires additional solvents to solubilize the fragrance and higher levels of preservatives. 

Typical cosolvents include methanol [67-56-17, ethanol [64-17-5] isopropyl alcohol [67-65-OJ, or toluene. The selection of cosolvents depends on the requirement of the formula and their interaction with other ingredients. Methanol is a common cosolvent in methylene chloride formulas since it has good solvency and is needed to swell ceUulose-type thickening agents. A typical methylene chloride formula used to strip wood is as follows (7). 

The normal salt, CH COONH, is a white, deUquescent, crystalline soHd, formula wt 77.08, having a specific gravity of 1.073. It is quite soluble in water or ethanol 148 g dissolve in 100 g of water at 4°C. The salt s solubiUty in water increases only slightly as temperature increases up to about 25 °C. The specific gravity of aqueous neutral ammonium acetate ranges from 1.022 to 1.092 as solution concentration increases from 10 to 50 wt % (4). The normal salt melts at 114°C, but decomposes before reaching its boiling point. 

Calciferol, when hydrogenated catalyticaky, took up 4 moles of hydrogen and gave a compound with the empirical formula C2gH 2D. Sodium in ethanol reduction gave a dihydroproduct that reacted with 3 moles of perbenzoic acid, thus demonstrating the derivative to have three double bonds. 

Specially Denatured Alcohol. Specially denatured alcohols (SDA) are formulations of ethanol containing denaturant substances that generally render them unfit for beverage use but do not limit their use in specified appHcations. To use a specially denatured alcohol, a manufacturer must apply to the BATE, giving quantitative formulas and processes. Specimen labels and a sample of the finished product are also required. Then, the prospective user must obtain a bond for the total amount of specially denatured alcohol on hand or in transit at any given time. 

The most widely known aleohol is ethyl aleohol, simply beeause it is the aleohol in aleoholie drinks. It is also known as grain aleohol, or by its proper name, ethanol. Ethyl aleohol is a eolorless, volatile liquid with a eharaeteristie odor and a pungent taste. It has a flash point of 55°F, is classified as a depressant drug, and is toxic when ingested in large quantities. Its molecular formula is CjHjOH. In addition to its presence in alcoholic beverages, ethyl alcohol has many industrial and medical uses, such as a solvent in many manufacturing processes, as antifreeze, antiseptics, and cosmetics.

Thereupon xylene is introduced again in vacuo at a temperature of 100°-105°C whereby all the methanol and the ethanol formed during re-esterification evaporates. The re-esterif-ication is continued under these conditions until a specimen of the reaction mass is clearly soluble in cold water, which occurs after about 2-3 hours. There is now obtained in almost quantitative yield the ester of the formula... 

The chloroform solution is concentrated and the residue recry stall i2ed from 270 cc of absolute ethanol. The pure 10-methoxy-4-(1 -methyl-4-piperldyl)-4H-ben2o[4,5] cyclohepta[1,2-b] -thiophen-4-ol base, having a melting point of 194°C to 196°C, is obtained in this manner. Microanalysis corresponds with the formula Q20H23NO2S. 

The chemical formula for ethanol is Cl L,Cl TOIL Ethanol is less toxic and more biodegradable than gasoline. For its octane boosting capability ethanol can be use as a fuel additive when blended with gasoline. 

Constitutional isomerism is not limited to alkanes—it occurs widely throughout organic chemistry. Constitutional isomers may have different carbon skeletons (as in isobutane and butane), different functional groups (as in ethanol and dimethyl ether), or different locations of a functional group along the chain (as in isopropylamine and propylamine). Regardless of the reason for the isomerism, constitutional isomers are always different compounds with different properties, but with the same formula. 

The usual method for finding the empirical formula is simply illustrated with ethanol, a compound containing only carbon, hydrogen, and oxygen. A weighed amount of the pure compound is completely burned in oxygen to give carbon dioxide (from the carbon) and water... 

Since the relative number of atoms of each element in the compound is the same as the relative number of moles of atoms of each element in the sample, we can say that the empirical formula of ethanol is... 

Now we know that the relative numbers of atoms in ethanol are two carbon to six hydrogen to one oxygen. We do not know yet whether the molecular formula is C2HsO, CjH 202, C6H 03, or some other multiple of the empirical formula, C2HeO. 

Satisfy yourself that this structure violates no bonding rules, and conforms to the empirical and molecular formula of ethanol. 

We have now found all possible structural formulas for the ethanol molecule. The oxygen atom is either directly bonded to one carbon atom or to two carbon atoms. Once a choice between these two possibilities is made, the structure of the rest of the molecule can be determined from the molecular formula and the bonding rules. The two possible structures are shown in Figure 18-2. Such compounds with the same molecular formula but different structural formulas are called structural isomers. The existence of the two compounds I and 2 was known long before their structures were clarified. Hence the existence of these isomers perplexed chemists for decades. Now we recognize the crucial impor-... 

So our problem is to decide whether ethanol has structure 1 or structure 2. How can we tell which is correct Let us see what preliminary ideas we can get from an examination of the structural formulas.
