The present invention is directed to a process for the manufacture of a compound of formula (III), comprising the step of reacting a compound of formula (I) with a compound of formula (II) in the presence of an acid catalyst and in a mixture of two solvents, wherein n is 1 or 2, and R1 and R3 are independently from each other H or C1-5-alkyl, and R2 is either H or C1-5-alkyl or C1-5-alkyloxy, preferably with the proviso that at least one of R1, R2 and R3 is H, and wherein the first of the two solvents is selected from ethylene carbonate, propylene carbonate, 1,2-butylene carbonate, gamma-butyrolactone and water, and the second of the two solvents is selected from hexane, cyclohexane, heptane, ortho-xylene, meta-xylene, para-xylene, mesitylene, pseudocumene, methyl tert-butyl ether, and toluene. The present invention is also directed to the compound of formula (III-3), as well as to the use of compounds of formula (III), especially to the use of compound of formula (III-3) and the use of compound of formula (III-4), as antioxidants, especially in feed, such as e.g. in feed for aquatic animals, in feed for terrestrial animals (especially pet food, feed for pigs and feed for poultry) and in feed for insects, and in feed ingredients, such as in fish meal, in poultry meal, in insect meal, and in PUFA-containing oils such as marine oil, microbial oil, fungal oil, algal oil and PUFA-containing plant oil The present invention is further directed towards feed and feed ingredients containing at least one compound of formula (III), especially containing a compound of formula (III-3) and/or a compound of formula (III-4).
本发明涉及一种制备式(III)化合物的方法,包括在两种溶剂的混合物中,在酸催化剂的存在下,将式(I)化合物与式(II)化合物反应,其中n为1或2,R1和R3独立地为H或C1-5-烷基,R2为H或C1-5-烷基或C1-5-烷氧基,优选至少其中之一为H,其中第一种溶剂选自碳酸乙烯酯、碳酸丙烯酯、1,2-丁二酸酯、γ-丁内酯和水,第二种溶剂选自己烷、环己烷、庚烷、邻二甲苯、间二甲苯、对二甲苯、三甲苯、假叔丁醚和甲苯。本发明还涉及式(III-3)化合物的制备方法,以及化合物式(III)的用途,特别是化合物式(III-3)和化合物式(III-4)作为抗氧化剂的用途,特别是在饲料中的用途,例如在水生动物饲料、陆生动物饲料(特别是宠物食品、猪饲料和禽饲料)和昆虫饲料中,以及在饲料成分中,例如在鱼粉、禽粉、昆虫粉和富含PUFA的油中,例如海洋油、微生物油、真菌油、藻油和富含PUFA的植物油。本发明还涉及至少含有一种式(III)化合物的饲料和饲料成分,特别是含有化合物式(III-3)和/或化合物式(III-4)的饲料和饲料成分。
