Benzyl Chloride. Benzyl chloride is manufactured by high temperature free-radical chlorination of toluene. The yield of benzyl chloride is maximized by use of excess toluene in the feed. More than half of the benzyl chloride produced is converted by butyl benzyl phthalate by reaction with monosodium butyl phthalate. The remainder is hydrolyzed to benzyl alcohol, which is converted to ahphatic esters for use in soaps, perfume, and davors. Benzyl salicylate is used as a sunscreen in lotions and creams. By-product benzal chloride can be converted to benzaldehyde, which is also produced directiy by oxidation of toluene and as a by-product during formation of benzoic acid. By-product ben zotrichl oride is not hydrolyzed to make benzoic acid but is allowed to react with benzoic acid to yield benzoyl chloride.

Carboxylic Ester Hydrolysis Butyl Benzyl Phthalate... 

Butyl benzyl phthalate is a mixed carboxylic acid ester formed by the condensation of phthalic acid with two different alcohols. No literature values could be found nor any directly applicable QSARs. Based on known reactivity of carboxylic acid esters, any acid hydrolysis should be very slow. Neutral hydrolysis, while reported in the literature for certain reactive esters, is not likely for the phthalate esters. The carboxylic acid esters are most labile to alkaline hydrolysis (Mabey and Mill, 1978). 

Still in the forties, butyl benzyl phthalate (BBP) was introduced by Monsanto Co. This ester is based on the monohydric alcohol n-butanol, but the benzyl group is derived from benzyl chloride rather then benzyl alcohol. This route was selected to make possible manufacture of pure coester which showed a better balance of properties than if made from the two alcohols. BBP was destined to make its mark in PVC, particularly in the flooring industry.

A considerable range of plasticizers is available but those used most commonly are phthalate esters such as dioctyl or dinonyl phthalate (DOP or DNP). If it should be necessary to reduce the temperature of fusion, or to increase the rate of fusion (as with some expandable plastisols) a fast-solvating plasticizer such as butyl benzyl phthalate may be employed. Besides primary plasticizers such as these, less efficient secondary plasticizers (like chlorinated paraffins) can be included with a view to reducing costs and improving flame retardance. 

Benzyl Chloride. The principal method for producing benzyl chloride involves the photochlorination of toluene, followed by neutralization and distillation. In 1999, 75 million lb of benzyl chloride were produced in the United States. About two-thirds was used to manufacture benzyl phthalates (mainly butyl benzyl phthalate), which are widely used as plasticizers. The other use was to make benzyl quarts. Benzyl chloride can also be used as raw material in the manufacture of benzyl alcohol, for use in photography, perfumes, and cosmetics. The production has increased considerably in Western Europe because of the greater use in solvents such as benzyl esters. But the U.S. production was stopped in 1999. 

Taking DOP as the reference standard of performance for low-temperature flex efficiency, other commercial plasticizers that are significantly better performers include linear dialkyl phthalates and alkyl esters of sebacic, azelaic, adipic, phosphoric, and epoxidized oleic acids. Significantly poorer performers are tricresyl phosphate, diphenyl phthalate, butyl benzyl phthalate, and branched dialkyl phthalates. 

Phthalate esters listed as EPA priority pollutants may be analyzed in wastewaters by U.S. EPA (1984) Methods 606 (GC), 625 (GC/MS), and 1625 (isotope dilution). Soils, sediments, groundwater, and hazardons wastes may be analyzed by GC using FID or ECD (Method 8060) or by GC/MS (Method 8270 or 8250) (U.S. EPA 1986). The primary and secondary characteristic ions to identify these compounds by GC/MS (electron-impact ionization) are as follows dimethyl phthalate, 149, 177, and 150 din-butyl phthalate, 149, 150, and 104 butyl benzyl phthalate, 149, 167, and 279 and din-octyl phthalate, 149, 167, and 43. Other phthalate esters may be analyzed by GC or GC/MS techniques. A fused-silica capillary column is suitable for the purpose.

Butyl benzyl phthalate, alkyl (C7-C9) benzyl phthalate, and Texanol benzyl phthalate are frequently selected to increase gloss of calendered films and to reduce fish eyes and other imperfections. Phosphate esters are selected for fire retardant, clear films having low temperature flexibility. 

As can be observed in this comparison, a variety of hardnesses, low temperature properties and elongations can be obtained, depending upon the choice of phthalate ester employed. Moreover, by comparing plasticizers such as butyl benzyl phthalate (BBP) to di-2-ethyl hexyl phthalate (DOP) one sees the higher solvating power of the BBP, reflected in the lower value of minimum flux femperature. So, for formulations where rapid plasticization is required, BBP is a good choice. However, the brittleness temperature for BBP formulations, based on the standard ASTM D-746 test protocol, is expected to be higher than that for DOP. 

Fast-fusing plasticizers enable the PVC material to be processed faster or at lower temperatures. Generally it is in the area of plasfisol applications where the uses of faster fusing plasticizers are preferred. Examples of fast-fiising plasticizers include butyl benzyl phthalate (BBP), citrates, the epoxidized fatty acid plasticizer methyl epoxy stearate, alkyl sulfonic acid esters of phenol, dibutyl phthalates and tere-phthalates, and dibenzoate esters and benzoate ester blends. It should be noted that the use of BBP in PVC has rapidly declined because of product restrictions, while the use of dibutyl phthalate (DBP) declined in North America and in Europe years ago because of its high volatility. 

Cushioned vinyl flooring is prepared by coating a substrate with various layers of plastisols. Traditionally these products used a mixture of plasticizers such as C7 to C9 phthalate esters, and are often found in blends with faster fusing plasticizers such as butyl benzyl phthalate (BBP) or dibenzoates. 

K-Flex dlbenzoate esters are often used to replace plasticizers such dlbutyl phtbalate and butyl benzyl phthalate where the formulator wishes to replace phthalate containing materials.
