Sulphurisation compounds of naphthalene, process for their preparation and their use |
| abstract |
n für eine ganze Zahl von 2 bis 10 steht, x 0 oder 1 bedeutet, x jedoch nur bei höchstens 10% der insgesamt vorliegenden sulfierten Naphthalinreste 1 ist und y 0 oder eine ganze Zahl oder gebrochene Zahl zwischen 0 und 2 bedeutet. Sulfation products of naphthalene of the formula in the n represents an integer from 2 to 10, x means 0 or 1, but x is only 1 in at most 10% of the total sulfonated naphthalene residues present and y means 0 or an integer or fractional number between 0 and 2. n n n They are produced by combining naphthalene with SO 3 in an inert solvent at temperatures from -40 to + 10 ° C in a ratio of SO 3 to naphthalene in the range of 3 to 5 moles of SO 3 per mole of naphthalene. The products are used for the production of naphthalene 1,5-disulfonic acid. |
