Ethylbutyrate

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). [Pg.452]

Plasticizers. Plasticizers are materials that soften and flexibilize inherently rigid, and even britde polymers. Organic esters are widely used as plasticizers in polymers (97,98). These esters include the benzoats, phthalates, terephthalates, and trimeUitates, and aUphatic dibasic acid esters. Eor example, triethylene glycol bis(2-ethylbutyrate) [95-08-9] is a plasticizer for poly(vinyl butyral) [63148-65-2] which is used in laminated safety glass (see Vinyl POLYMERS, poly(vinyl acetals)). Di(2-ethyUiexyl)phthalate [117-81-7] (DOP) is a preeminent plasticizer. Variation of acid and/or alcohol component(s) modifies the efficacy of the resultant ester as a plasticizer. In phthalate plasticizers, molecular sizes of the alcohol moiety can be varied from methyl to tridecyl to control permanence, compatibiUty, and efficiency branched (eg, 2-ethylhexyl, isodecyl) for rapid absorption and fusion linear (C6—Cll) for low temperature flexibiUty and low volatility and aromatic (benzyl) for solvating. Terephthalates are recognized for their migration resistance, and trimeUitates for their low volatility in plasticizer appHcations. [Pg.396]

In contrast to this, sample presentation is thoroughly investigated. On behalf of the Ministry of Housing, Physical Planning and Environment, TNO investigated the influence of flow rate in relation to dilution factor, both analytically and sensorically. The flow rate varied from 6 to 35 1/min. Propane concentrations were measured at the back of the nose of an artificial head through which 20 1/min. was sucked continuously. Sensory measurements were carried out with butanol and ethylbutyrate. The results are summarized in figure 1. Based on this research 16 1/min. was recommended as the minimal sample flow rate. [Pg.78]

Hydrolytic cleavage plays an important role in the metabolic fate of both carbromal (4.210) and bromisoval (4.213). A product of hydrolysis of carbro-mal, 2-bromo-2-ethylbutyramide (4.211), was isolated from the urine of patients intoxicated with carbromal as well as from the urine of rats, mice, and dogs dosed with the drug [138], A suspected further metabolite is 2-bromo-2-ethylbutyric acid (4.212). Other metabolic transformations of carbromal involve hydroxylation and debromination. [Pg.154]

We experimented firstly with a Phenomenex Rezex ROA-Organic Acid 300 X 7.8 mm column with a Rezex Organic Acid 50 x 7.8 mm guard column the mobile phase was 0.013 N (0.0065 M) H2SO4. UV detection was at 215 nm, the flowrate 0.6 ml min, column temperature 35°C and injection volume 20 pi. The internal standard was 2-ethylbutyric acid. The lactic acid peak was preceded by a partially overlapping, probably succinic acid peak the... [Pg.161]
