Di-p-tolyl Succinate.-Succinic acid (11 g., 0.09 inole) and
p-cresol (20 g., 0.18 mole) were placed in a 200-ml. roundbottom
flask equipped with a thermometer and a reflux
condenser protected by a drying tube. The flask and contents
were heated to 115-120" by means of an oil-bath.
Phosphorus oxychloride (16 g., 0.1 mole) was added clropwise
to the hot mixture. Toward the end of the addition
the vigorous bubbling due to the evolution of hydrogen
chloride subsided, and on continued heating only a negligible
amount of bubbling was observed. After heating for two
to three hours at 115-120°, the dark reaction mixture was
allowed to cool, whereupon a reddish-brown crystalline
material formed on top of a black viscous material. The
crystalline material was scraped away from the black resin
and mixed with 250 g. of a 1 : 1 mixture of ice and water.
The dark orange crystals were then filtered, dried, and recrystallized
from ethanol to give 17 g. (63.4%) of a light
orange crystalline material, m.p. 114-1 18'. This material
was pure enough to be used in the Fries rearrangement.
Three additional recrystallizations from ethanol afforded a
white crystalline material, m.p. 119-12O0
l-Hydroxy-4-methylanthraquinone.-An attempted rearrangement
of di-p-tolyl phthalate (3.5 g., 0.01 mole) was
carried out as described above for di-p-tolyl succinate, except
that the temperature was held at 100" for 16 hours.
After the chlorobenzene was removed by steam distillation,
a red-brown solid remained in the distillation flask. This
solid was collected and recrystallized from glacial acetic
acid to give I-hydroxy-4-methylanthraquinone as redbrown
needles; yield 0.53 g. (14%), m.p. 171-172'. A
further recrystallization of a sample of this crude product
from ethanol gave bright orange-yellow needles, m.p. 173",
reported** m.p. 175-176'

整篇都不能翻译吗？还是只是有一点翻译不出来？只需把难点拿出来求助，这样才好得到回复

太长了！

此文献应该很老了.因为把实验操作都说的很详细.其实工艺很简单.一会我给你翻译,那些用多大的反应瓶等简单的操作就忽略了(懒得打字).只要你是做合成的应该一看就懂. 少等,先开会.

1.琥珀酸二对甲苯酯
琥珀酸(11 g., 0.09 inole),对甲苯酚(20 g., 0.18 mole)加入200ml反应平中,装回流管,升至115-120度,滴加三氯氧磷(16 g., 0.1 mole),加完后在115-120°反应2-3小时.冷却,加入250 g. 1 : 1 的冰水,过滤,得深黄色固体,乙醇精制的浅黄色固体17 g. (63.4%).m.p. 114-118,(可以进行下一步投料).再用乙醇精致3次,得到白色固体,m.p. 119-12O

实验写的很详细，做化工基本应该看的懂才对
