Dehydration of 1-butanol to 1- and 2-butenes

Q: What is the major product from the dehydration of 1-butanol?

A: From Brown, Foote, and Iverson, with H2SO4/heat
The products are trans-2-butene (56%), cis-2-butene (32%), and 1-butene (12%).

Similarly, Brown, Foote, and Iverson record that 2-butanol with 85% H3PO4 gives 2-butene (80%) and 1-butene (20%)
