There are numerous further appHcations for which maleic anhydride serves as a raw material. These appHcations prove the versatiHty of this molecule. The popular artificial sweetener aspartame [22839-47-0] is a dipeptide with one amino acid (l-aspartic acid [56-84-8]) which is produced from maleic anhydride as the starting material. Processes have been reported for production of poly(aspartic acid) [26063-13-8] (184—186) with appHcations for this biodegradable polymer aimed at detergent builders, water treatment, and poly(acryHc acid) [9003-01-4] replacement (184,187,188) (see Detergency).

Starch monophosphates are quite useful in foods because of their superior freeze—thaw stabiUty. As thickeners in frozen gravy and frozen cream pie preparations, they are preferred to other starches. A pregelatinized starch phosphate has been developed (131) which is dispersible in cold water, for use in instant dessert powders and icings and nonfood uses such as core binders for metal molds, in papermaking to improve fold strength and surface characteristics, as a textile size, in aluminum refining, and as a detergent builder.

Diphosphinomethane is a valuable intermediate to form methylene diphosphonic acid by oxidation with nitric acid (see Sec. IV). The alkali salts of methyl-enediphosphonic acid offer sequestering properties and are used as detergent builders. [Pg.569]

The following reaction sequence was used to obtain methyl hydroxymethanediphosphonic acid. This compound is widely used as a water hardness sequestering agent and detergent builder. Triethyl chloride was reacted with acetyl chloride to give diethylacetylphosphonate, followed by a conversion with diethyl phosphite and sodium. After completion of this reaction the substance was hydrolyzed with HC1 to yield hydroxymethanediphosphonic acid, [93,94], as shown in Eqs. (49)-(51) ... [Pg.571]

Tetraphosphonate compounds are another type of calcium-sequestering agent and detergent builder. Propane 1,1,3,3-tetraphosphonate can be formed by reaction of the sodium carbanion of tetraisopropylmethylene-diphosphonate with dichloromethane, then hydrolyzed and converted to the wanted salt [97,98] see Eq. (54) ... [Pg.572]

Zeolite A is by far the most widely produced synthetic zeolite, with an annual production of some 1.3 million tonnes. As may be expected from this large volume its main use is not as a catalyst but as a detergent builder (Box 4.2). Since about 1970 the use of zeolite catalysts has provided huge economic and environmental benefits to the bulk chemical and petroleum refining industries. [Pg.92]
