Mascibilis aqua et maxime Organicum solvents, resinat, cera, etc.; Misciblewith modice Zein, apricis, Petrolatum; Immiscible cum anhydrous glycerin, gluten, casin, Arabica gummi et Soybean dapibus. Combustibilis.
Eget proprietatibus	Γ-valerolactone est dulcis, herbaceis odor.
Uses	Balneum mori (cooptos agente), fregit fluidorum, cutting olea et solvendo ad adhesives, Insecticides et lacquers.
Praeparatio	Per reductionem Levulinic acid sequitur cyclization.
Profile	Modice toxicus a ingestion. Et cutis irritans. Mutationem data nuntiavit. Combustibilis liquida cum patere calor aut flamma; potest agere cum oxidizing materiae. Pugnare ignis Usus aqua, spumam, CO2, sicca eget. Cum succensa est corrumpuntur emit acres fumus et vexo fumus.
Purificacionis modi	Purificare in -lactone Per repetita fractis distillation [Boorman & Linstead j chem Soc Soc (DLXXVII, DLXXX MCMXXXIII]. IR: MAX MDCCXC (CS2), MDCCLXXV (Chcc3) cm-I [Jones et al. Can J Cham III VII MMVII MCMLIX]. Et BF3, complexu distilit ad 110-111O / 20mm [reppe et al. Justus Liebigs Ann Cham DXCVI CLXXIX MCMLV]. Est propria conversione ad -hydroxy-n-Valamide in curatio cum NH3, M 51.5-52O (a tardus evaporatio de chcl3 solutio). [Cf. Beilstein XVII II CCXXXV, XVII ego CXXXI, XVII II CCLXXXVIII, XVII III / IV (IV) CLXXVI, 17/9 24.]
