Navigate parenthood with the help of the Raising Curious Learners podcast. CS2 once was manufactured by combining carbon (or coke) and sulfur at high temperatures. [20] Typical recommended TLV is 30 mg/m3, 10 ppm. For many years carbon disulfide was manufactured by the reaction of charcoal with sulfur vapour at temperatures of 750°–1,000° C (1,400°–1,800° F), but, by the mid-20th century, that process had been superseded, especially in the United States, by one based on the reaction of natural gas (principally methane) with sulfur.. We assume you are converting between grams CS2 and mole. Its boiling point is 46.3° C (115.3° F) and its freezing point -110.8° C (-169.2° F); its vapour, which is heavier than air, is ignited with extraordinary ease.
