Genetically Engineered Free Forests (GEFF), a group assembled specifically in response to the meeting. In addition, on the opening night of the meeting the only field trial of transgenic trees in the UK, testing trees engineered to suppress lignin production (CAD antisense), was destroyed. The meeting opened with a keynote address by Ron Sederoff (North Carolina University, USA) in which he succinctly
A method for producing 4-hydroxydiphenyl ether,
characterized by reacting diphenyl ether with an acylating agent in the presence of an acid catalyst to obtain a 4-acyldiphenyl ether represented by the formula (1):
wherein R represents a substituted or unsubstituted alkyl or aryl group,
reacting the 4-acyldiphenyl ether with a peroxide to obtain a 4-acyloxydiphenyl ether represented by the formula (2):
wherein R has the same meaning as defined above, and solvolyzing the ester bond of the 4-acyloxydiphenyl ether, is provided.
一种生产 4-羟基二苯醚的方法、
其特征是在酸催化剂存在下,使二苯醚与酰化剂反应,得到由式(1)表示的 4-酰基二苯醚:
其中 R 代表取代或未取代的烷基或芳基、
将 4-乙酰基二苯醚与过氧化物反应,得到式(2)代表的 4-乙酰氧基二苯醚:
其中 R 的含义与上述定义相同,并溶解 4-乙酰氧基二苯醚的酯键。
