View Patent ↗Compounds according to formula (I) or formula (II) wherein R 1 and R 2 , independently from each other, are chosen among hydrocarbons having from 1 carbon atom up to 30 carbon atoms, with the proviso that at least one of R 1 and R 2 are chosen among hydrocarbons having at least 8 carbon atoms, and A is a halogen. Use of compounds as hydrophobing agent, such as sizing agent.
1. A compound according to formula (I)
wherein each of R 1 and R 2 , independently from each other, is a hydrocarbon having from 16 carbon atoms up to 30 carbon atoms and up to 30 carbon atoms, and A is a halogen; or
a compound according to formula (II)
wherein each of R 1a and R 2a , independently from each other, is an aliphatic hydrocarbon having at least 16 carbon atoms, and A is a halogen; or
a mixture of compounds of formula (I) and formula (II).
2. A method for producing a compound or a mixture of compounds chosen among compounds of formula (I), formula (II), and a mixture thereof, according to claim 1 , the method comprising reacting compounds of formula (III) and of formula (IV), compounds of formula (III) being represented by:
