The leader of DuPont s effort was Wallace H Carothers who reasoned that he could reproduce the properties of silk by constructing a polymer chain held together as is silk by amide bonds The neces sary amide bonds were formed by heating a dicar boxylic acid with a diamine Hexanedioic acid adipic acid) and 1 6 hexanediamme hexamethylenedi-amine) react to give a salt that when heated gives a polyamide called nylon 66 The amide bonds form by a condensation reaction and nylon 66 is an example of a condensation polymer...

Mliphatic dibasic acids such as succinic acid, adipic acid, azelaic acid, and sebacic acids have also been used to make alkyd resins. Their linear chain stmcture lends higher flexibiUty and lower viscosity to the resin as compared to the rigid aromatic rings of phthaUc acids. [Pg.33]

Carboxylic acids with one acid group are known as monobasic acids while those with two acid groups are dibasic acids. All acids with more than one acid group are in the class of polybasic acids. The simplest organic acid, formic acid, is responsible for the irritation of bee and ant stings. Vinegar is a 5% solution of acetic acid in water. The acetic acid is responsible for the characteristic sour taste. Citric acid, found in citrus fruits and used in soft drinks, is a tribasic acid with three carboxylic acid groups. The dibasic acid, adipic acid, is a major component of nylon. [Pg.65]

Numerous chemical intermediates are oxygen rich. Methanol, acetic acid and ethylene glycol show a O/C atomic ratio of 1, as does biomass. Other major chemicals intermediates show a lower O/C ratio, typically between 1/3 and 2/3. This holds for instance for propene and butene glycols, ethanol, (meth)acrylic acids, adipic acid and many others. The presence of some oxygen atoms is required to confer the desired physical and chemicals properties to the product. Selective and partial deoxygenation of biomass may represent an attractive and competitive route compared with the selective and partial oxidation of hydrocarbon feedstock. [Pg.28]

Nylon-66 is made by the condensation polymerization of the dicarboxylic acid adipic acid, and 1,6-diaminohexane, an amine. (The number 66 comes from the fact that each of the two reactants contains six carbon atoms.) This reaction results in the formation of amide bonds between monomers, as shown in Figure 2.13. Condensation polymers that contain amide bonds are called nylons or polyamides. Condensation polymers that contain ester bonds are called polyesters. Polyesters result from the esterification of diacids and dialcohols. [Pg.83]

There are dozens of organic acids that are used in petrochemicals processing. But there are three that account for more than 70% of the total volume—acetic acid, adipic acid, and the phthalic acids. These compounds have little in common with each, other besides the carboxyl signature group, written as -COOH, drawn as... [Pg.255]

Bionolle is an aliphatic polyester as shown in Fig. 2. We have two grades for Bionolle poly(butylene succinate) (PBS) and poly(butylene succinate/adipate) (PBSA), the copolymer of 1,4-butandiol and succinic acid/adipic acid. We call PBS the 1000 series, and PBSA the 3000 series. PBSA with higher adipic acid content is the 5000 series. [Pg.288]

The repeating units in nylon 66 and in most step reaction polymers consist of residues from both reactants. The following equation shows the synthesis of nylon 66 in this case the reactants are a dicarboxylic acid (adipic acid) and a diamine (1,6-hexanediamine). [Pg.13]
