摘要:
A process is disclosed which comprises reacting at elevated temperature (a) a copolymer of an olefin and a monomer having the structure ##STR1## wherein X and X.sup.1 are the same or different provided that at least one of X and X.sup.1 is such that the copolymer can function as a carboxylic acylating agent and (b) a succinimide prepared from an acyclic hydrocarbyl substituted succinic acylating agent and a polyamine wherein the hydrocarbyl substituted succinic acylating agent is prepared by reacting a polyolefin and an acylating agent of formula I under conditions such that at least 75 mole % of the starting polyolefin is converted to the hydrocarbyl-substituted succinic acylating agent. Hydrocarbyl substituted succinic acylating agents derived from high reactivity PIB's are preferred.
摘要:
This invention relates to a process for the production of a polyoxyalkylene derivative of a phenolic resin, by reacting under base-catalyzed conditions the phenolic resin with the appropriate alkylene oxide(s) so that the polyoxyalkylation is carried out by: A) using a phenolic resin which has a water content of less than 0.5% w/w, B) reacting the phenolic resin initially with about one mole of the alkylene oxide(s) per mole of the resin in the absence of a base catalyst in an inert atmosphere at a temperature below 140.degree. C. until the partial pressure of the alkylene oxide(s) reactant is substantially neutralized, and C) reacting the product from step (B) above with the remainder of the alkylene oxide(s). These derivatives are good emulsifiers and demulsifers.
摘要:
This invention relates to a process for producing low molecular weight phenol-aldehyde resin which has predominantly 4 phenolic units in a chain and in which the phenolic ring has a substituent R which is an alkyl group and optionally contains methylol groups on either end of the chain, by reacting formaldehyde with p-alkyl phenol in the presence of ammonia as base in a liquid reaction medium. The resins can be used in producing demulsifiers.
