НАдо глядеть у нас

Я нашёл у себя в библиотеке, только ни сканера, ни фотоаппарата сейчас нет. Попробую отдолжить и сфотографировать на днях. Там есть ссылка, как я понял, на первоначальный британский патент 1960 года. Может он где в инете есть?!

Brit Pat 964097 30/12/1960.

Вот я недолго поискал и нашёл кое-что:

Abstract of GB 964097 (A)
Translate this text
Carboxylic acid derivatives are obtained by treating an aliphatic or alicyclic ketone peroxide with acrylonitrile or an acrylic ester of a C1- 5 alkanol and HCl or HBr in the presence of ferrous or cuprous ions, e.g. at -10 DEG C. to + 10 DEG C. The ketone peroxides are generally formulated as 1-hydroxy-hydroperoxides. The two types of reaction involved are: <FORM:0964097/C1/1> and <FORM:0964097/C1/2> where R1 is CN or COOR (R being C1- 5 alkyl) and R1 and R2 are e.g. alkyl groups; and the corresponding reactions with HBr and with other alicyclic ketone peroxides. In examples, (1), (11) cyclopentanone peroxide, acrylonitrile and HCl give HOOC(CH2)5CHClCN, which is hydrolysed and esterified to CH3OOC(CH2)5CHClCOOCH3 this is hydrolysed to the free acid, and the latter hydrogenated to suberic acid; (2), (3) and (7) methyl ethyl ketone or diethyl ketone peroxide, acrylonitrile and HCl give a -chlorovaleronitrile, which is hydrolysed to a -chlorovaleric acid; (4) methyl hexyl ketone peroxide, acrylonitrile and HCl give a product which is hydrolysed to a -chlorononanoic acid; (5) methyl heptyl ketone peroxide, acrylonitrile and HCl similarly give a -chlorodecanoic acid; (6) methyl ethyl ketone peroxide, acrylonitrile and HBr similarly give a -bromovaleric acid; (8) methyl ethyl ketone peroxide, methyl acrylate and HCl give methyl a -chlorovalerate; (9) cyclohexanone peroxide, treated as in (1), gives successively HOOC(CH2)6 CHClCN and CH3OOC(CH2)6CHClCOOCH3; (10) cyclohexanone peroxide, butyl acrylate and HCl gives the butyl ester of a -chloroazelaic acid; (12) Methyl a -chloroazelate is hydrolysed and hydrogenated to produce azelaic acid. Specifications 884,761 and 890,141 are referred to.

Тот же патент, только на немецком. Это то что нужно?

[Arkadii_Tarasevych]

Да, судя по абстракту из Chem Zentralblatt это - то же изобретение.

[SergSam]

Огромное спасибо!!! Да, это оно
Очень благодарен за Ваш труд

[Arkadii_Tarasevych]

Пожалуйста!:)
