Residual amounts of 7 volatile organic compounds, i.e., toluene, ethylbenzene, xylene, hexamethylacetone, 3-ethoxypropionate, 6-methyl-2-heptanone and benzylalc. in solidified paint were determined by GC-MS. The sample was crushed and extracted (by ASE) thrice with acetone consecutively, at 50°C for 3 min in each extraction HP-5MS column was used for separation Linear relationships between values of peak area and mass concentration of the 7 volatile organic compounds were kept in definite ranges, with detection limits (3S/N) in the range of 0.01-1.35μg. Using blank sample as matrix, test for recovery was made by standard addition method, and values of recovery obtained were in the range of 84.4%-104%, with values of RSD’s (n = 6) in the range of 0.80%-13%. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Computed Properties of C7H14O3).
Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
