Bisanhydrohexitol derivatives having terminal mercapto groups are provided. Additionally, curable compositions that include these mercapto-containing bisanhydrohexitol derivatives, cured compositions prepared from the curable compositions, and articles containing the cured compositions are provided. More specifically, the curable compositions are epoxy-based formulations and the mercapto-containing bisanhydrohexitol derivatives function as curing agents for epoxy resins.

isosorbide‐2‐O‐propyl sulfonic acid sodium salt and exo‐2‐O‐alkyl isosorbide‐5‐O‐propyl sulfonic acid sodium salt) with straight alkyl chains (hexyl, octyl, decyl, and dodecyl) were synthesized from isosorbide derivedfrom biomass, through steps of allylation, alkylation, and sulfonation. The selectivity and efficiency of the reactions were optimized by adjusting the solvent, catalyst, reactant molar ratio

본 발명은 아이소소바이드 유도체 화합물에 관한 것이다. 본 발명의 아이소소바이드 유도체 화합물은 우수한 광학적 특성과 열적 특성을 갖고 있어 고분자 소재로 응용이 가능하며, 천연물 기반의 친환경, 무독성 소재로서 환경호르몬이 발생할 수 있는 비스페놀 A 기반의 고분자소재를 대체할 수 있다.
Each of the two hydroxyl groups of isosorbide can be alkylated selectively, either by direct alkylation with benzyl chloride or allyl bromide according to the reaction conditions, or by a three-step procedure involving selective monoacetylation, alkylation with four different reagents, and finally deacetylation. Monobutyl and monomethyl derivatives from isosorbide are also described.
