Thermal decomposition of symmetrical and unsymmetrical peroxides of dicarboxylic acids was written by Goldschmidt, Stefan;Dachs, Karl. And the article was included in Chemische Berichte in 1955.HPLC of Formula: 18891-13-9 The following contents are mentioned in the article:

ClCO(CH₂)₂CO₂Me (150 g.) and 40 g. NaOH in 250 cc. H₂O added to 220 cc. 15% H₂O₂ at 0° gives (MeO₂CCH₂CH₂CO)₂O₂ (I), m. 77° (decomposition). Bz₂O₂ (10 g.) in 600 cc. absolute Et₂O treated at -2° with a solution of 1.2 g. Na in 100 cc. 96% alc. and 70 cc. ice water and the mixture washed with Et₂O gives an aqueous solution of 4.7 g. (94.4%) BzO₂Na. A solution (70 cc.) of Na₂CO₃, saturated at 15° and cooled to 0°, treated with 4 cc. ClCO(CH₂)₂CO₂Me, then with the above solution of BzO₂Na, gives benzoyl 3-carbethoxypropionyl peroxide (II), oily liquid, decompose 69-70°. Similarly were prepared the following acyl benzoyl peroxides (acyl, decomposition temperature, and % yield given): EtO₂C(CH₂)₃CO (III), 76-8°, 92; EtO₂C(CH₂)₄CO (IV), 83°, 98; EtO₂C(CH₂)₅CO (V), 91°, -. Refluxing HO₂C(CH₂)₆CO₂H, in 5 mol alc. while the solution is treated with HCl gas gives EtO₂C(CH₂)₆CO₂Et, which with an equivalent amount of HO₂C(CH₂)₆CO₂H yields EtO₂C(CH₂)₆CO₂H, and with SOCl₂ gives EtO₂C(CH₂)₆COCl (VI). A diagram is given of the thermal. decomposition apparatus Heating 50.5 g. 98.9% I in 172 g. AcOH at 100° gives 6 g. MeO₂CEt, b. 79.5°, 160 g. AcOH, b. 117°, 3.5 g. MeO₂CCH₂CH₂OAc, b₁₉ 96-8°, 9.5 g. MeO₂C(CH₂)₄CO₂Me, b₁₉ 123-4°, and 10 g. MeO₂ CCH₂CH₂CO₂CH₂CH₂CO₂Me (VII), b_1.5 149-50°. Heating CH₂:CHCN in a sealed tube with concentrated HCl gives ClCH₂CH₂CO₂H, yielding with CH₂N₂ the Me ester, which, heated with AgO₂C(CH₂)₄CO₂Me, gives VII, b₁ 149°. The decomposition of the unsym. peroxides without a solvent produces, in each case, a small amount of BzOH (BzOMe, b₃₀ 89-91°) and 4-PhC₆H₄CO₂H, m. 219°. Heating 24.2 g. II without a solvent gives, in addition to the above, 1.15 mols. CO₂, 0.3 g. EtO₂CCH:CH₂, EtO₂C(CH₂)₄CO₂Et, b₃₀ 141°, and 17 g. (85%) EtO₂CCH₂CH₂OBz, b₁ 97-100°. Similarly, 26 g. III gives 0.4 g. EtO₂CCH₂CH:CH₂, b. 118° (amide, m. 72°), 0.3 g. EtO₂C(CH₂)₆CO₂Et, b₁₁ 141°, and 17.3 g. (79%) EtO₂C(CH₂)₃OBz (VIII), b₁ 103-6°. Treating VIII with alkali, acidifying, extracting, and heating the product 8 h. at 200° gives γ-butyrolactone (IX), b₃₀ 102°; acidification of the alk. solution yields BzOH, m. 122°. Heating 29.5 g. IV as above gives 1.13 mol CO₂, 0.4 g. EtO₂CCH₂CH₂CH:CH₂, b. 142-4°, 0.3 g. EtO₂C(CH₂)₈CO₂Et, b₁₂ 166°, and 19.7 g. BzO(CH₂)₄CO₂Et (X). Hydrolysis of X gives EtOH, BzOH, and δ-valerolactone, b₁₁ 110°. Heating 31 g. V gives 1.19 mol CO₂, 0.5 g. CH₂:CH(CH₂)₄CO₂Et (XI), b₃₀ 68°, 0.5 g. EtO₂C(CH₂)₁₂CO₂Et (XII), b_0.8 50°, and 22.4 g. (83%) BzO(CH₂)₆CO₂Et (XIII). Heating XIII with 4N KOH gives HO(CH₂)₆CO₂H as a sirup. Heating 26.7 g. IV in 580 g. Me₂NPh gives BuCO₂Et, b. 144°, 7.9 g. BzOMe, b₁₂ 90°, 8.1 g. EtO₂C(CH₂)₄CO₂Me, b₁₂ 123° [HO₂C(CH₂)₄CO₂H, m. 152°], 3.2 g. δ-valerolactone, b₁₄ 113°, BzOH, m. 122°, 90 g. Me₂NPh, and 11 g. (p-Me₂NC₆H₄)₂, m. 195°. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9HPLC of Formula: 18891-13-9).

Ethyl methyl adipate (cas: 18891-13-9) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.HPLC of Formula: 18891-13-9
