A method for protecting the surface of a metal surface which comprises applying to said surface an organophosphorus compound of the formula ##STR1## wherein A IS 0 OR 1 R is a branched or unbranched chained bivalent alkylene radical of 1 to 12 carbon atoms which is substituted or unsubstituted and can contain in the chain structure --O--, --S--, ##STR2## R' is a branched or unbranched alkyl radical of 1 to 12 carbon atoms which can be halogen substituted and can contain in the chain structure ##STR3## X is an epoxy ring, halogen, alkylene, carboxylic acid ester residue, amino, isocyanato, isothiocyanato, urea, thiourea, urethano, alkyl substituted thio radical or the radical or a heterocyclic ring containing O, S, or N in the ring structure; a new organophosphorus compounds having the formula set forth above and more particularly defined by specific chemical structures.
一种保护金属表面的方法,包括将式为##STR1##的有机磷化合物涂覆于该表面上,其中A为0或1,R为1至12个碳原子的支链或直链二价烷基,可以是取代或未取代,并且可以在链结构中含有--O--、--S--、##STR2##,R'为1至12个碳原子的支链或直链烷基,可以被卤素取代,并且可以在链结构中含有##STR3##,X为环氧环、卤素、烷基、羧酸酯残基、氨基、异氰酸酯基、异硫氰酸酯基、脲基、硫脲基、脲酯基、取代烷基硫基基或含有O、S或N的杂环环结构中的基团;一种新的有机磷化合物,其具有上述式子,并且更具体地由特定的化学结构定义。
