PVB resins are also compatible with a limited number of plasticizers and resins. Plasticizers (qv) improve processibility, lower T, and increase flexibihty and resiUency over a broad temperature range. Usehil plasticizers include dibutyl and butyl benzyl phthalates, tricresyl and 2-ethylhexyl diphenyl phosphates, butyl ricinoleate, dibutyl sebacate, dihexyl adipate, triethylene glycol di-2-ethylbutyrate, tetraethylene glycol diheptanoate, castor oil, and others (64-73).

Other chemicals that are common in different RSL are phthalates. Phthalates are usually used as softening agents in plastics to obtain the required flexibility. The most common phthalates included on restriction lists for the leather industry are bis(2-ethylhexyl)phthalate (DEHP), benzyl butyl phthalate (BBP), dibutyl phthalate (DBP), di- isononyl phthalate (DINP), D- isodecyl phthalate (DIDP) and di-n-octyl phthalate (DNOP). All these chemicals are included on the SVHC list (Candidate List), and currently (2012) there is a proposal to restrict the placing of products containing DEHP, BBP and DBP on the market in the EU. 

As well as aiding processing, a major function of plasticisers is to extend the operating temperature range by improving low temperature flexibility. The majority of demand in CR and NBR is satisfied by general purpose phthalate plasticisers di-2-ethylhexyl phthalate (DEHP), diisononyl phthalate (DINP) and diisodecyl phthalate (DIDP). However, a wide variety of speciality plasticisers, mainly esters, are marketed within the rubber industry. The majority of these have linear molecular structures giving them better low temperature performance than the phthalates. Examples of such plasticisers are di-2-ethylhexyl adipate (DOA), butyl carbitol adipate, di(butoxyethoxyethyl) adipate (BCA), and di-2-ethylhexyl sebacate (DOS).

The results of analyses of sediment samples taken from the River Rhine are listed in Table 4.1. From Table 4.1 it is seen that for the sediment of the River Rhine di-2-ethylhexyl phthalate and di-ra-butyl phthalate concentrations generally are between 2 and 50ppm.

Ethyl alcohol has been made by the hydration of ethylene (9) since 1930. Like isopropyl alcohol, part of the output is used as a solvent, but most is converted to other oxygenated chemicals. Its most important raw material use is conversion to acetaldehyde by catalytic air oxidation. Acetaldehyde, in turn, is the raw material source of acetic acid, acetic anhydride, pentaerythritol, synthetic n-butyl alcohol (via aldol condensation), butyraldehyde, and other products. Butyraldehyde is the source of butyric acid, polyvinyl butyral resin, and 2-ethylhexanol (octyl alcohol). The last-named eight-carbon alcohol is based on the aldol condensation of butyraldehyde and is used to make the important plasticizer di-2-ethylhexyl phthalate. A few examples of the important reactions of acetaldehyde are as follows ... 

Sample Concentration Experiments. A CLLE quality assurance blank was run by extracting 90 L of Milli-Q water with three CLLE samplers in a parallel configuration and concentrating the composited extract to 4 mL by Kudema-Danish evaporation. The 22,500-fold concentrate was analyzed by GC-flame ionization detection (GC-FID) and GC-MS. Thirty-two peaks were observed by using GC-FID analysis, but because of their low concentrations, only four contaminants were identified by GC-MS cyclohexene, 2-cyclohexen-1-one, n-butyl phthalate, and bis(2-ethylhexyl) phthalate. Cyclohexene is a solvent preservative that has been identified in commercial high-purity methylene chloride (16), and 2-cyclohexen-l-one is its air oxidation product. The phthalates are ubiquitous laboratory contaminants and have also been identified in commercial methylene chloride (17). 

A study of infant formulae showed that phthalates were present in the majority of samples analysed.70 However, 31 percent of the samples did not contain any of the seven individual phthalates analysed. These were di-isopropyl phthalate (DIPP), dipropyl phthalate (DPP), di-iso-butyl phthalate (DIBP), dibutyl phthalate (DBP), benzyl butyl phthalate (BBP), di-2-ethylhexyl phthalate (DEHP) and di-isodecyl phthalate. Only DBP, BBP and DEHP were present at measurable concentrations. DEHP was the most abundant individual phthalate and was found at concentrations ranging from 0.05 to 0.44 mg/kg. The dietary exposures to all phthalates were below the relevant TDIs.
